PZTA92

Changjing · Bipolar (BJT) · SOT-223

PZTA92 from Changjing, in a SOT-223. 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 separate pin limit, and the emitter-base breakdown voltage V(BR)EBO is -5 V minimum at IE=-0.1 mA.
2 COLLECTOR passive Collector terminal; the absolute maximum collector-base and collector-emitter voltages are -300 V, with continuous collector current limited to -0.2 A (pulsed -0.5 A).
3 EMITTER passive Emitter terminal of the PNP transistor; the absolute maximum emitter-base voltage is -5 V.
