BC807W

Changjing · Bipolar (BJT) · SOT-323

BC807W from Changjing, 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	BASE	input	Base terminal of the PNP transistor; the datasheet gives the device limits VEBO -5 V and IC -0.5 A (continuous) and tests base current IB = -50 mA at IC = -500 mA for VCE(sat).
2	EMITTER	passive	Emitter terminal of the PNP transistor; the emitter-base breakdown voltage VEBO is rated -5 V with IE = -1 µA, and the device maximum ratings are VCBO -50 V and VCEO -45 V.
3	COLLECTOR	passive	Collector terminal of the PNP transistor; the datasheet rates the collector-emitter voltage VCEO at -45 V, the collector current IC at -0.5 A continuous, and the collector power dissipation PC at 0.2 W.
