Changjing · Bipolar (BJT) · TO-92
2N5401-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 emitter-base breakdown voltage V(BR)EBO is -5 V minimum and the emitter-base voltage rating VEBO is -5 V. |
| 2 | BASE | passive | Base terminal of the PNP transistor; the emitter cut-off current IEBO is specified at VEB = -3 V with a maximum of -50 nA, and the base drive used for saturation tests is IB = -5 mA at IC = -50 mA. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the ratings are VCBO -160 V, VCEO -150 V, IC -0.6 A and PC 625 mW. |
