SS8550 from hongjiacheng, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Base terminal of the PNP BJT. Drive current into base (negative relative to emitter for PNP forward-active operation). VBE(sat) max -1.2V at IC=-800mA, IB=-80mA. |
| 2 | E | passive | Emitter terminal of the PNP BJT. Typically tied to the higher potential (e.g. VCC) in high-side switching or common-emitter configurations. VEBO max -5.0V. |
| 3 | C | passive | Collector terminal of the PNP BJT. VCBO max -40V, VCEO max -25V, IC max -1.5A. VCE(sat) max -0.5V at IC=-800mA, IB=-80mA. |
