**OSEN** · Bipolar Transistors - BJT · TO-220F

2SC4793-OSEN from OSEN, in a TO-220F. 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 | B | input | Base terminal of the NPN transistor; Emitter-Base Voltage (VEBO) is limited to 5 V and continuous base current (IB) to 0.1 A. |
