LMBT5401LT1G

LRC · Bipolar (BJT) · SOT-23

LMBT5401LT1G 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 transistor; the device maximum ratings are V_CEO -150 Vdc, V_CBO -160 Vdc, V_EBO -5.0 Vdc and continuous collector current I_C -500 mAdc.
2 EMITTER passive Emitter terminal; the emitter-base breakdown voltage V(BR)EBO is -5.0 Vdc minimum at I_E = -10 µAdc.
3 COLLECTOR passive Collector terminal; the datasheet limits collector-emitter voltage V_CEO to -150 Vdc and collector-base voltage V_CBO to -160 Vdc.
