MMBT9012H

ST Semtech · Bipolar (BJT) · SOT-23

MMBT9012H from ST Semtech, 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 input Base terminal of the PNP transistor; the datasheet's absolute maximum emitter-base voltage (-VEBO) is 5 V.
2 Emitter passive Emitter terminal of the PNP transistor; the device absolute maximum collector current (-IC) is 500 mA.
3 Collector passive Collector terminal of the PNP transistor; absolute maximum collector-base voltage (-VCBO) is 40 V and collector-emitter voltage (-VCEO) is 30 V.
