Changjing · Bipolar (BJT) · SOT-323
2SA1576A 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; emitter-base breakdown voltage V(BR)EBO is -6 V minimum at IE=-50μA, IC=0. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the absolute maximum emitter-base voltage VEBO is -6 V. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; absolute maximum ratings are VCBO -60 V, VCEO -50 V and collector current IC -150 mA, with PC 200 mW. |
