BCP55-16-MS

MSKSEMI · Bipolar Transistors - BJT · SOT-223

BCP55-16-MS from MSKSEMI, in a SOT-223. 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; the datasheet's VCE(sat) test uses IB=50mA at IC=500mA.
2 COLLECTOR passive Collector terminal; rated VCBO 45/60/100 V (by part) and IC 1 A continuous.
3 EMITTER passive Emitter terminal; rated VEBO 5 V.
