Circuit applications:
- LED switching from microcontroller GPIO: base resistor (~1kΩ) + NPN transistor drives LED cathode to GND
- High-current LED driver: single transistor can switch ~100mA — enough for several LEDs in parallel
- PWM dimming: transistor switches fast enough for flicker-free PWM at 1kHz+
- TO-92 pinout (flat face): EBC — Emitter, Base, Collector — verify your datasheet
Sold individually (1 unit per quantity ordered).
