**Infineon Technologies** · MOSFETs · TO-252

IRFR3806TRPBF from Infineon Technologies, in a TO-252. 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 terminal of the HEXFET; VGS is rated -20 V to +20 V (absolute maximum ±20 V). |
| 2 | D | passive | Drain terminal; continuous drain current is 43 A at TC = 25°C with VGS = 10 V, and VDSS is 60 V. |
| 3 | S | passive | Source terminal; continuous body-diode source current is 43 A (pulsed 170 A) and the diode forward voltage is 1.3 V maximum at IS = 25 A. |
