Changjing · Bipolar (BJT) · TO-92
MPS2907A 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 emitter-base breakdown voltage V(BR)EBO is -5 V minimum and the emitter-base cut-off current IEBO is -10 nA maximum at VEB=-3V. |
| 2 | BASE | passive | Base terminal of the PNP transistor; the base-emitter saturation voltage VBE(sat) is -1 V maximum at IC=-150mA, IB=-15mA. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the datasheet rates the collector-emitter voltage VCEO at -60 V and the continuous collector current IC at -0.6 A. |
