MMST2222A-TP

MCC(Micro Commercial Components) · Bipolar (BJT) · SOT-323

MMST2222A-TP from MCC(Micro Commercial Components), in a SOT-323. 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 B input Base of the NPN transistor; VEBO is limited to 6 V and the base-emitter saturation voltage is 0.6 to 1.2 V at IC=500mA, IB=50mA.
2 E passive Emitter of the NPN transistor; the emitter-base breakdown voltage V(BR)EBO is 6 V minimum.
3 C passive Collector of the NPN transistor; VCEO is 40 V, VCBO is 75 V and the maximum collector current ICM is 0.6 A.
