2N4403-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 of the PNP transistor, rated with an emitter-base voltage VEBO of -5 V and continuous collector current IC of -600 mA for the device. |
| 2 | BASE | input | Base of the PNP transistor, where the datasheet's emitter-base breakdown V(BR)EBO is -5 V minimum at IE=-100 uA, and VBE(sat) is -0.95 V max at IC=-150 mA, IB=-15 mA. |
| 3 | COLLECTOR | passive | Collector of the PNP transistor, rated with collector-base voltage VCBO of -40 V and collector-emitter voltage VCEO of -40 V, with total power dissipation PC of 0.625 W. |
