KNB3306C from KIA Semicon Tech, in a TO-263. 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 | Gate | input | MOSFET gate control terminal; the datasheet rates gate-source voltage VGS at ±25 V as an absolute maximum. |
| 2 | Drain | passive | Drain terminal of the N-channel MOSFET; the datasheet rates drain-source voltage VDSS at 68 V and continuous drain current ID at 80 A (TC=25°C). |
| 3 | Source | passive | Source terminal of the N-channel MOSFET; the datasheet rates maximum continuous diode forward current IS at 80 A. |
