LMUN2214LT1G

LRC · Digital Transistors · SOT-23

LMUN2214LT1G from LRC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BASE input Base terminal of the NPN bias-resistor transistor, which has a built-in input resistor R1 of 10 kΩ (7 to 13 kΩ minimum to maximum per the electrical characteristics).
2 EMITTER passive Emitter terminal of the NPN transistor, rated for a collector-emitter voltage VCEO of 50 V and a continuous collector current IC of 100 mA.
3 COLLECTOR passive Collector terminal of the NPN transistor, rated for a collector-base voltage VCBO of 50 V and a continuous collector current IC of 100 mA.
