BC817 6B 160-400 from DOWO, 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 | BASE | input | Base terminal of the BC817 NPN transistor; the datasheet gives only the pin assignment and no pin-specific limit (device limits: VCEO 45 V, IC 0.5 A continuous, PC 0.3 W). |
| 2 | EMITTER | passive | Emitter terminal of the BC817 NPN transistor; the datasheet gives only the pin assignment and no pin-specific limit (device limits: VEBO 5 V, IC 0.5 A continuous, PC 0.3 W). |
| 3 | COLLECTOR | passive | Collector terminal of the BC817 NPN transistor; the datasheet gives only the pin assignment and no pin-specific limit (device limits: VCBO 50 V, VCEO 45 V, IC 0.5 A continuous). |
