FOSAN · Bipolar (BJT) · SOT-23
BC846C from FOSAN, 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, at the bottom-left lead in the package diagram; VEBO max is 6 V for BC846. |
| 2 | E | passive | Emitter of the NPN transistor, at the bottom-right lead in the package diagram; collector current IC max is 100 mA. |
| 3 | C | passive | Collector of the NPN transistor, at the single top lead in the package diagram; VCEO max is 65 V and VCBO max is 80 V for BC846. |
