KMBTA94

KEXIN · Bipolar (BJT) · SOT-23

KMBTA94 from KEXIN, 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 passive Base terminal of the PNP transistor; the emitter-base breakdown voltage VEBO is rated -5 V.
2 Emitter passive Emitter terminal of the PNP transistor; the absolute maximum emitter-base voltage VEBO is -5 V.
3 Collector passive Collector terminal of the PNP transistor; rated for VCEO = -400 V and continuous collector current IC = -200 mA (pulsed ICM = -300 mA).
