LMUN2134LT1G

LRC · Digital Transistors · SOT-23

LMUN2134LT1G 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 (22 kΩ for LMUN2134LT1G) with R2 of 47 kΩ from base to emitter.
2 EMITTER power_in Emitter (ground) of the PNP bias resistor transistor, with maximum collector-emitter voltage VCEO of 50 Vdc.
3 COLLECTOR output Collector (output) of the PNP bias resistor transistor, rated for VCBO 50 Vdc, VCEO 50 Vdc and IC 100 mAdc maximum.
