SP35N120CTF

Siliup · Silicon Carbide Field Effect Transistor (MOSFET) · TO-247-3L

SP35N120CTF from Siliup, in a TO-247-3L. 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; recommended gate-source drive is -5/+18 V, with absolute maximum VGS of -10/+22 V.
2 D passive Drain; rated for 1200 V drain-source voltage and 35 A continuous current at Tc=100℃ (65 A at Tc=25℃).
3 S passive Source; main current return terminal of the MOSFET, with pulsed drain current up to 130 A.
