BCP53-16-MS from MSKSEMI, in a SOT-223. 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 of the PNP transistor; the datasheet lists VEBO of -5 V maximum and V(BR)EBO of -5 V at IE=-10μA. |
| 2 | COLLECTOR | passive | Collector of the PNP transistor; continuous collector current is -1 A maximum and VCEO is -80 V for the BCP53 type. |
| 3 | EMITTER | passive | Emitter of the PNP transistor, the common terminal for the base-emitter and collector-emitter voltage ratings. |
