5630/5730 SMD LEDs are mid-power surface-mount emitters measuring 5.6mm × 3.0mm (5630) or 5.7mm × 3.0mm (5730). Despite the slightly different dimensions, the two designations refer to functionally interchangeable packages with the same PCB footprint, and the terms are used interchangeably across the industry. At 0.5W rated power, the 5630/5730 fills the gap between the lower-power PLCC packages (PLCC-6 / 5050 at ~0.2W) and true high-power LEDs (1W, 3W, 10W emitters with dedicated star PCBs and heatsinks). The 5630/5730 is the standard emitter in commercial-grade LED strip lighting, panel light arrays, troffer retrofit kits, and utility-grade area lighting — anywhere you need more lumens per emitter than a 5050 can deliver but without the thermal management complexity of a high-power LED. We stock 5630/5730 LEDs in warm white, natural white, and cool white.

Commercial and industrial LED panel lighting is the primary application for 5630/5730 emitters. Office ceiling troffers, flat-panel lights, commercial retail display lighting, grocery store shelf lighting, parking garage fixtures, gas station canopy lights, and warehouse bay lights all use arrays of 5630/5730 LEDs mounted on aluminum-core PCBs (MCPCBs). A single 5630/5730 LED at 150mA produces approximately 45–65 lumens (depending on color temperature and manufacturer bin), which means a panel of 60–100 LEDs delivers 3,000–6,000 lumens — enough to replace a 2×4 fluorescent troffer. LED retrofit kit manufacturers and sign companies buy 5630/5730 emitters in volume for these applications. The lumens-per-watt efficiency of a well-binned 5630/5730 (typically 80–130 lm/W at rated current) makes it competitive with higher-power emitters for distributed-source luminaire designs where many lower-power LEDs spread across a large area produce more uniform illumination than a few high-power point sources.

LED strip manufacturing and repair is the second-largest demand driver. Commercial-grade 5630/5730 LED strips offer significantly higher brightness than standard 5050 strips — typically 40–60 lumens per LED versus 12–22 lumens for a 5050 — making them the choice for applications where the strip must serve as a primary light source (under-cabinet kitchen lighting, cove lighting in commercial lobbies, display case illumination) rather than just accent lighting. When individual LEDs fail on a 5630 strip, the affected section dims or goes dark entirely. Replacing the failed emitter with a fresh 5630/5730 LED restores full brightness to that segment without replacing the entire strip run. DIY LED fixture builders and custom strip fabricators also buy individual 5630/5730 LEDs to populate custom rigid or flexible PCBs at specific densities and color temperatures that off-the-shelf strips do not offer.

Thermal management is a key consideration at 0.5W per emitter — significantly more important than for lower-power packages like 0805 or even 5050. The 5630/5730 package includes an exposed metal thermal pad on the underside that must be soldered to a copper pad on the PCB for proper heat dissipation. Aluminum-core PCBs (MCPCBs) are the standard substrate for 5630/5730 arrays because the aluminum base acts as a built-in heatsink, conducting heat away from the LED junction far more effectively than standard FR4 fiberglass board. For strip applications on FR4 flex PCBs, the strip should be mounted on an aluminum channel extrusion or metal surface to provide a secondary heat path. Without adequate thermal management, junction temperature rises above the rated maximum (typically 110–130°C), which accelerates lumen depreciation, causes color shift toward blue, and shortens LED lifespan from 50,000+ hours to a fraction of that. If you are designing a custom fixture, ensure the thermal pad is connected to a copper pour on your PCB that ultimately couples to a heatsink or metal enclosure.

Electrical specifications: 5630/5730 LEDs are single-color, single-die emitters (not multi-die like the 5050 RGB). Forward voltage for white variants is typically 2.8–3.4Vf at a rated drive current of 150mA (0.5W). Some manufacturer bins rate at 120mA for a derating margin; check the product page for the exact current rating of each SKU. At 150mA, a single LED dissipates approximately 0.45–0.5W. A current-limiting resistor is required unless you are using a constant-current LED driver (which is the preferred method for arrays of 5630/5730 LEDs in series). Use our LED Resistor Calculator to find the exact value for your supply voltage.html">LED resistor calculator handles the math. For multi-LED arrays, wire LEDs in series (3–4 LEDs per series string on 12V, with a small ballast resistor) to improve efficiency, and use a constant-current driver for the best lumen output and color consistency.

Soldering 5630/5730 LEDs is straightforward given the relatively large package, but the thermal pad adds a step that smaller packages do not have. For hand soldering: apply solder paste to the thermal pad and the two electrical pads on the PCB, position the LED with tweezers, then reflow with a hot-air station or hot plate. The thermal pad cannot be effectively soldered with a hand iron alone (you cannot reach the pad once the LED is placed), so solder paste and hot-air or hot-plate reflow is strongly recommended. For a single-LED repair on an existing strip, apply flux and fresh solder paste to the pads, place the new LED, and reflow with hot air at 300–360°C at low airflow. For production arrays, standard SMT reflow profiles (lead-free peak ~245°C or leaded peak ~225°C) work well. JLCPCB and PCBWay stock 5630/5730 LEDs for automated assembly on aluminum-core PCBs.

Choosing between 5630/5730 and other packages: if you need an RGB-capable SMD LED rather than single-color white, step to PLCC-6 / 5050 (RGB, 6-pin, ~0.2W) or PLCC-4 / 3528 (RGB, 4-pin, smaller). If 0.5W is not enough and you need true high-power output (1W, 3W, 10W per emitter) with a star PCB and active heatsinking, see our high-power LEDs. For indicator-level brightness in a smaller package, 0805, 1206, or PLCC-2 / 3528 packages are more appropriate. For through-hole LEDs, see DIP LEDs and diffused LEDs. The SMD LEDs parent category lists all surface-mount packages we carry.

Frequently Asked Questions

The two names describe nearly identical packages: 5630 = 5.6mm × 3.0mm; 5730 = 5.7mm × 3.0mm. The 0.1mm difference is within manufacturing tolerance, and the PCB footprint is the same. The industry uses both terms interchangeably. Both are rated at approximately 0.5W and share the same electrical and thermal characteristics. When ordering, either designation will work on the same PCB pad layout.
A 5630/5730 LED at 150mA produces approximately 45–65 lumens (single white die at 0.5W). A 5050 white LED (three parallel dies at 60mA total, ~0.2W) produces 12–22 lumens. So a single 5630/5730 is roughly 2–5× brighter than a single 5050, at about 2.5× the power consumption. The 5630/5730 is designed to be a functional light source (primary illumination), while the 5050 is typically used for accent and decorative lighting.
Yes — at 0.5W per LED, thermal management matters. The package has an exposed metal thermal pad on the bottom that must be soldered to a copper pad on your PCB for heat transfer. For arrays of multiple LEDs, use an aluminum-core PCB (MCPCB) or mount the board on an aluminum heatsink / channel extrusion. Without adequate heat dissipation, junction temperature rises, reducing brightness, shifting color temperature, and shortening LED lifespan dramatically. Even single-LED applications should ensure the thermal pad is properly soldered to a copper pour.
You can solder the two electrical pads with a hand iron, but the thermal pad on the underside of the LED cannot be reached with an iron once the LED is placed. For a proper thermal connection, solder paste and reflow (hot air at 300–360°C or a hot plate) is strongly recommended. Apply solder paste to the thermal pad and both electrical pads, position the LED with tweezers, and reflow. Without the thermal pad soldered, the LED will still light up but may overheat under sustained current because heat cannot conduct to the PCB.
For arrays of 5630/5730 LEDs, a constant-current LED driver is the preferred approach. Wire LEDs in series strings (3–4 LEDs per string on a 12V supply, with a small ballast resistor for current matching) and power each string from a constant-current driver rated at 150mA (or your target drive current). For large panels, dedicated LED driver ICs (like the AL8860, PT4115, or Meanwell LPC series) handle regulation, dimming, and thermal protection automatically. Using a constant-current driver instead of a simple resistor improves efficiency and ensures consistent brightness across all LEDs regardless of temperature-induced Vf shifts.
We stock 5630/5730 LEDs in warm white (~3000–3500K, soft incandescent-like glow for residential and hospitality applications), natural white (~4000–4500K, neutral tone for offices and retail), and cool white (~5500–6500K, crisp blue-leaning white for task lighting, industrial, and commercial fixtures). The listed color temperatures are approximate and can vary slightly by manufacturer lot. For color-critical applications, check the specific binning information on each product page.
