AD-BCP68-16

Changjing · Bipolar Transistors - BJT · SOT-223

AD-BCP68-16 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; the datasheet lists VEBO of 5 V maximum and a DC current gain hFE of 100 to 250 for the -16 rank.
2 COLLECTOR passive Collector of the NPN transistor; the datasheet lists VCEO of 20 V, VCBO of 32 V and a continuous collector current IC of 1 A.
3 EMITTER passive Emitter of the NPN transistor, the reference terminal for VBE and VCE; the datasheet gives a collector power dissipation of 1 W.
