MPSA44G-T92-A-B

UTC(Unisonic Tech) · Bipolar (BJT) · TO-92-3

MPSA44G-T92-A-B from UTC(Unisonic Tech), in a TO-92-3. 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 terminal of the NPN transistor; in the TO-92 T92-A variant (MPSA44G-T92-A-B) pin 1 is the emitter, and the datasheet gives no pin-specific electrical limit beyond the device ratings (VCEO 400 V, IC 300 mA, VEBO 6 V).
2 C passive Collector terminal of the NPN transistor; in the TO-92 T92-A variant pin 2 is the collector, and the device limits apply (VCEO 400 V for MPSA44, IC 300 mA, peak ICM 1000 mA).
3 B passive Base terminal of the NPN transistor; in the TO-92 T92-A variant pin 3 is the base, and the datasheet gives no pin-specific limit beyond the device ratings (VEBO 6 V).
