Changjing · Bipolar (BJT) · SOT-23

2SA1313 from Changjing, 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 BASE input Base terminal of the PNP transistor; the datasheet rates the emitter-base voltage VEBO at -5 V and the collector current IC at -500 mA continuous.
2 EMITTER passive Emitter terminal of the PNP transistor; the emitter-base breakdown V(BR)EBO is -5 V minimum at IE=-100μA.
3 COLLECTOR passive Collector terminal of the PNP transistor; the datasheet rates VCEO at -50 V and PC at 200 mW.
