PXTA94

SY(顺烨) · IC · SOT-89

PXTA94 from SY(顺烨), in a SOT-89. 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, with emitter-base voltage VEBO rated at -5 V and continuous collector current limited to -0.2 A.
2 COLLECTOR passive Collector terminal, rated for collector-base voltage VCBO of -400 V and collector-emitter voltage VCEO of -400 V, with continuous collector current IC of -0.2 A and peak ICM of -0.3 A.
3 EMITTER passive Emitter terminal of the PNP transistor, with emitter-base breakdown V(BR)EBO of -5 V minimum and emitter-base voltage VEBO rated at -5 V.
