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). |
