IXTP24N65X2 from Littelfuse, in a TO-220-3. 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 | Gate of the MOSFET; continuous VGSS is limited to ±30 V, with transient VGSM up to 40 V, and VGS(th) is 3.0 to 5.0 V at ID = 250 µA. |
| 2 | Drain | passive | Drain, also connected to the metal tab; VDSS is 650 V and continuous ID25 is 24 A at TC = 25°C. |
| 3 | Source | passive | Source terminal; the intrinsic body diode is rated IS = 24 A continuous and ISM = 96 A pulsed, with VSD of 1.4 V typical at IF = IS. |
