BC846A-7-F

Diodes Incorporated · Bipolar (BJT) · SOT-23

BC846A-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; the top-view pin-out shows B at the bottom-left lead, and the part is rated for VEBO of 6.0V (BC846) and IC of 100mA continuous.
2 E passive Emitter; the top-view pin-out shows E at the bottom-right lead, and the part has a peak emitter current IEM of 200mA.
3 C passive Collector; the top-view pin-out shows C as the single lead on top, and the BC846A has VCEO of 65V and VCBO of 80V, with IC of 100mA continuous and 200mA peak.
