BC817-25-AU_R1_000A1 from PANJIT International, 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; Emitter-Base voltage VEBO limited to 5 V and DC collector current IC up to 500 mA is controlled by it. |
| 2 | E | passive | Emitter of the NPN transistor; Emitter-Base breakdown voltage BVEBO is 5 V minimum at IE=1 uA. |
| 3 | C | passive | Collector of the NPN transistor; VCEO is 45 V, VCBO is 50 V, IC is 500 mA DC and 1000 mA pulsed. |
