HSCT040W120G34

HXY MOSFET · Silicon Carbide Field Effect Transistor (MOSFET) · TO-247-4L

HSCT040W120G34 from HXY MOSFET, in a TO-247-4L. 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 Drain passive Drain terminal, also connected to the metal TAB; the device is rated VDS max 1200 V (VGS = 0 V, ID = 100 μA) with continuous ID of 78 A at VGS = 15 V, TC = 25 °C.
2 Power Source passive Power source terminal carrying the main drain current return, kept separate from the driver source pin to reduce gate ringing and switching losses.
3 Driver Source passive Separate driver source pin for the gate drive return, provided as the optimized package feature that minimizes gate ringing.
4 Gate input Gate input with stated limits of -10/+25 V dynamic (AC, f > 1 Hz) and -5/+20 V static (VGSop).
