PZTA94

Changjing · Bipolar (BJT) · SOT-223

PZTA94 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 emitter-base breakdown V(BR)EBO of -5 V minimum and emitter-base voltage VEBO of -5 V.
2 COLLECTOR passive Collector terminal; rated at VCBO and VCEO of -400 V, continuous collector current IC of -0.2 A and pulsed ICM of -0.3 A.
3 EMITTER passive Emitter terminal of the PNP transistor; the datasheet specifies emitter-base voltage VEBO of -5 V and emitter-base breakdown V(BR)EBO of -5 V minimum.
