Changjing · Bipolar (BJT) · TO-92
MPSA56-TA from Changjing, in a TO-92. 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 | EMITTER | passive | Emitter terminal of the MPSA56 PNP transistor; the datasheet's absolute maximum emitter-base voltage is -4 V and emitter-base breakdown is specified at IE=-0.1 mA. |
| 2 | BASE | passive | Base terminal of the MPSA56 PNP transistor; base drive is referenced to the emitter, with base-emitter voltage specified at about -1.2 V max at IC=-100 mA, VCE=-1 V. |
| 3 | COLLECTOR | passive | Collector terminal of the MPSA56 PNP transistor; collector-base voltage is limited to -80 V and continuous collector current to -0.5 A. |
