LMBT5087LT1G

LRC · Bipolar (BJT) · SOT-23

LMBT5087LT1G 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 low-noise transistor; the datasheet gives no pin-specific limit, and the device-level maximum collector-base voltage is -50 Vdc with emitter-base voltage of -3.0 Vdc (VEBO).
2 EMITTER passive Emitter terminal of the PNP transistor; the datasheet gives no pin-specific limit, and the device-level emitter-base voltage rating is -3.0 Vdc (VEBO).
3 COLLECTOR passive Collector terminal of the PNP transistor; the datasheet gives no pin-specific limit, and the device-level collector-emitter voltage rating is -50 Vdc (VCEO) with continuous collector current of -50 mA.
