BC847A-7-F

Diodes Incorporated · Bipolar Transistors - BJT · SOT-23

BC847A-7-F from Diodes Incorporated, in a SOT-23. 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 NPN transistor; shown at the bottom left of the top-view pin-out, with VEBO limited to 6.0 V for BC847 and 100 mA continuous collector current rating for the device.
2 E passive Emitter of the NPN transistor; shown at the bottom right of the top-view pin-out, with peak emitter current IEM of 200 mA.
3 C passive Collector of the NPN transistor; the single lead on the top side of the top-view pin-out, with VCEO of 45 V and continuous IC of 100 mA for BC847.
