MPSA92-TA
Changjing · Bipolar (BJT) · TO-92
MPSA92-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 PNP transistor; the datasheet rates the emitter-base voltage VEBO at -5 V and the emitter-base breakdown voltage V(BR)EBO at -5 V (IE = -100 µA). |
| 2 | BASE | passive | Base terminal; the base-emitter saturation voltage VBE(sat) is -0.9 V at IC = -20 mA and IB = -2 mA. |
| 3 | COLLECTOR | passive | Collector terminal; the datasheet rates VCBO at -310 V, VCEO at -305 V, continuous collector current IC at -200 mA and pulsed ICM at -500 mA. |
