BCV48 from Nexperia, in a SOT-89. 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 | E | passive | Emitter of the PNP Darlington transistor; VEBO limit is -10 V (open collector). |
| 2 | C | passive | Collector of the PNP Darlington transistor; max collector current -500 mA, VCES -60 V, VCBO -80 V. |
| 3 | B | passive | Base of the PNP Darlington transistor; peak base current limited to -100 mA (single pulse, tp ≤ 1 ms). |
