KTA1504Y from Changjing, 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 | BASE | input | Base of the PNP transistor; the datasheet gives VEBO of -5 V and IB of -10 mA in the saturation test condition. |
| 2 | EMITTER | passive | Emitter of the PNP transistor; the datasheet gives emitter-base breakdown voltage of -5 V at IE=-100 µA. |
| 3 | COLLECTOR | passive | Collector of the PNP transistor; the datasheet gives VCEO of -50 V and a maximum collector current IC of -150 mA. |
