SS8050W from TWGMC, in a SOT-323. 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 | passive | BASE terminal of the SS8050W NPN transistor; the datasheet gives no separate base limit, and the base is tested with VEB = 5 V (ICBO/IEBO max 0.1 μA). |
| 2 | EMITTER | passive | EMITTER terminal of the SS8050W NPN transistor, with absolute maximum emitter-base voltage VEBO of 5 V. |
| 3 | COLLECTOR | passive | COLLECTOR terminal of the SS8050W NPN transistor, rated for 1.5 A continuous collector current (IC), 25 V collector-emitter voltage (VCEO) and 0.2 W collector power dissipation (PC). |
