IXTP3N120

Littelfuse IXYS · MOSFETs · TO-220AB-3

IXTP3N120 from Littelfuse IXYS, in a TO-220AB-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 control terminal, with a maximum continuous gate-source voltage VGSS of 20 V and a transient VGSM of 30 V.
2 Drain passive Drain terminal, rated for VDSS of 1200 V and continuous drain current ID25 of 3 A at TC = 25C; the drain is also connected to the metal tab.
3 Source passive Source terminal, the reference for gate drive, with a source-drain diode continuous current IS of 3 A at VGS = 0 V.
