PXTA92

Nexperia · Bipolar Transistors - BJT · SOT-89

PXTA92 from Nexperia, 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 E passive Emitter of the PNP transistor; emitter-base voltage limited to -5 V (VEBO) with collector open.
2 C passive Collector of the PNP transistor (also the tab/mounting pad); VCEO -300 V, VCBO -300 V, IC max -100 mA, ICM -200 mA.
3 B passive Base of the PNP transistor; peak base current IBM limited to -100 mA.
