2SA1037-Q from Yangzhou Yangjie Elec Tech, 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; emitter-base voltage limit VEBO is -6 V and DC current gain hFE is 120-270 for the Q rank at VCE=-6V, IC=-1mA. |
| 2 | E | passive | Emitter of the PNP transistor; emitter-base breakdown voltage is -6 V at IE=-50μA. |
| 3 | C | passive | Collector; collector current is limited to -0.15 A, VCBO -60 V and VCEO -50 V, with 200 mW collector power dissipation. |
