Changjing · Bipolar (BJT) · SOT-323
2SA1579 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 | passive | Base terminal of the PNP transistor; the datasheet gives no pin-specific limit, and the device-level ratings apply (VEBO -5 V, IC -50 mA, PC 100 mW, Tj/Tstg -55 to +150 ℃). |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the datasheet gives no pin-specific limit, and the device-level ratings apply (VEBO -5 V, IC -50 mA, PC 100 mW, Tj/Tstg -55 to +150 ℃). |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the datasheet gives no pin-specific limit, and the device-level ratings apply (VCBO -120 V, VCEO -120 V, IC -50 mA, PC 100 mW). |
