**HXY MOSFET** · MOSFETs · TO-252-2L

IRLR8726T from HXY MOSFET, in a TO-252-2L. 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; the datasheet limits VGS to ±20 V (absolute maximum) and specifies VGS(th) of 1 V min, 1.6 V typ, 2.5 V max at VGS=VDS, ID=250 uA. |
| 2 | D | passive | Drain terminal; the datasheet rates VDS at 30 V and continuous drain current ID at 80 A (TC=25℃), with 320 A pulsed. |
| 3 | S | passive | Source terminal; the reference for VGS, with continuous source current IS rated at 80 A and pulsed source current ISM at 320 A. |
