BCV46TA from Diodes Incorporated, in a SOT-23. 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 Darlington; base current is limited to -100 mA and the emitter-base voltage to -10 V. |
| 2 | E | passive | Emitter of the PNP Darlington; VEBO is -10 V maximum. |
| 3 | C | passive | Collector of the PNP Darlington; BCV46 VCEO is -60 V and VCBO is -80 V, with -500 mA continuous and -800 mA peak current. |
