**YFW** · MOSFETs · TO-251

YFW80N04AMJ from YFW, in a TO-251. 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 | G | input | Gate control input with a maximum gate-source voltage of ±20 V and a threshold of 1.1 V to 2.4 V, and operation with gate voltages as low as 4.5 V. |
| 2 | D | passive | Drain terminal rated for 40 V drain-source voltage and 80 A continuous drain current, with 350 A pulsed drain current. |
| 3 | S | passive | Source terminal, with a maximum body-diode continuous current of 80 A. |
