**YONGYUTAI** · Bipolar Transistors - BJT · SC-70

2SC4083PWT1G from YONGYUTAI, in a SC-70. 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 | BASE | input | Base terminal of the transistor; the datasheet gives no separate pin-level limit, with the device ratings applying as listed in the absolute maximum table (VCBO 20 V, VCEO 11 V, VEBO 3 V, IC 50 mA, PC 0.15 W). |
| 2 | EMITTER | passive | Emitter terminal; the datasheet specifies emitter-base breakdown voltage BVEBO of 3 V minimum at IE = 10 µA. |
| 3 | COLLECTOR | passive | Collector terminal; the datasheet specifies collector-emitter breakdown voltage BVCEO of 11 V minimum at IC = 1 mA and collector current IC of 50 mA maximum. |
