BCX53-10 from Changjiang Electronics Tech (CJ), in a SOT-89-3L. 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 PNP transistor; the datasheet's maximum emitter-base voltage is -5 V and it gives no separate base pin rating. |
| 2 | COLLECTOR | passive | Collector terminal; the maximum ratings give collector current -1 A and collector power dissipation 500 mW. |
| 3 | EMITTER | passive | Emitter terminal; the maximum emitter-base voltage is -5 V per the absolute maximum ratings. |
