BC856BW-7-F

Diodes Incorporated · Bipolar (BJT) · SOT-323

BC856BW-7-F from Diodes Incorporated, 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 of the PNP transistor; bottom-left pin in the top-view pin-out, with VEBO limited to -5.0 V.
2 E passive Emitter of the PNP transistor; bottom-right pin in the top-view pin-out, with peak pulse emitter current IEM of -200 mA.
3 C passive Collector of the PNP transistor; single top pin in the top-view pin-out, rated -100 mA continuous (-200 mA peak) and VCEO of -65 V for BC856.
