BC846CW

CBI · Bipolar (BJT) · SOT-323

BC846CW from CBI, in a SOT-323. 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 B input Base; NPN transistor control terminal, with VEBO of 6 V max for BC846W and IC of 100 mA max.
2 E passive Emitter; the datasheet gives an emitter-base voltage rating of 6 V for BC846W and a total power dissipation of 200 mW.
3 C passive Collector; VCEO is 65 V max and IC is 100 mA (200 mA peak) for BC846W.
