AD-BCP55-16

Changjing · Bipolar (BJT) · SOT-223

AD-BCP55-16 from Changjing, 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 of the NPN transistor; continuous base current is limited to 100 mA (200 mA peak) and VEBO is 5 V max.
2 COLLECTOR passive Collector of the NPN transistor; for AD-BCP55 VCBO is 60 V, VCEO is 60 V, and continuous collector current is 1 A (2 A peak).
3 EMITTER passive Emitter of the NPN transistor; VEBO is 5 V max.
