BCX5116TA from Diodes Incorporated, in a SOT-89-3. 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 | B | input | Base of the PNP transistor; the pin-out drawing shows it as the bottom lead in top view. |
| 2 | C | passive | Collector (BVCEO -45V for BCX51, IC -1A continuous, ICM -2A peak), also connected to the exposed collector tab/pad used for heat sinking. |
| 3 | E | passive | Emitter of the PNP transistor; the pin-out drawing shows it as the top lead in top view, and VEBO max is -5V. |
