L2SA1037AKRLT1G

LRC · Bipolar (BJT) · SOT-23

L2SA1037AKRLT1G 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 PNP transistor; the datasheet gives no separate pin rating, and the device limit for emitter-base voltage is V_EBO -6.0 V.
2 EMITTER passive Emitter terminal of the PNP transistor; the emitter-base breakdown voltage is V(BR)EBO -6 V minimum at I_E = -50 µA.
3 COLLECTOR passive Collector terminal of the PNP transistor; the datasheet rates collector-emitter voltage V_CEO at -50 V and continuous collector current I_C at -150 mA.
