2SA1586 from Changjing, in a SOT-323. 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, with emitter-base breakdown voltage V(BR)EBO of -5 V minimum at IE=-100µA and a maximum emitter-base voltage VEBO of -5 V. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor, rated for a maximum emitter-base voltage VEBO of -5 V and a maximum collector current IC of -150 mA shared with the collector. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor, rated for a maximum collector-emitter voltage VCEO of -50 V and a maximum collector current IC of -150 mA, with total collector power dissipation PC of 100 mW. |
