# XR100N20G

**XNRUSEMI** · MOSFETs · TO-263

XR100N20G from XNRUSEMI, 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 | G | input | Gate; the gate-source voltage must stay within ±20 V, and the gate threshold is 3 V min to 5 V max at ID=250uA. |
| 2 | D | passive | Drain, which is also the package tab; drain-source voltage is rated 200 V and continuous drain current is 100 A at TC=25°C. |
| 3 | S | passive | Source; continuous current is 100 A at TC=25°C, and the body diode carries a continuous source current of up to 65 A. |
