LMUN2113LT1G

LRC · Digital Transistors · SOT-23

LMUN2113LT1G 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 (input) of the PNP bias resistor transistor, connected through series resistor R1 (47 kΩ for LMUN2113) with R2 (47 kΩ) base-emitter resistor.
2 EMITTER passive Emitter (ground) of the PNP bias resistor transistor; the datasheet shows it as the ground reference of the circuit.
3 COLLECTOR passive Collector (output) of the PNP bias resistor transistor, rated VCEO 50 Vdc and IC 100 mAdc maximum.
