2SA1588-Y from TOSHIBA, in a SOT-323(SC-70). 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; base current is limited to −50 mA and emitter-base voltage to −5 V maximum. |
| 2 | E | passive | Emitter of the PNP transistor; VEBO is −5 V maximum. |
| 3 | C | passive | Collector of the PNP transistor; VCBO is −35 V, VCEO is −30 V and IC is −500 mA maximum. |
