BCZ120N40M1

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

BCZ120N40M1 from Bestirpower, 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 of the MOSFET, rated for 1200 V drain-to-source (VDSS) and 60 A continuous drain current at TC = 25℃ (VGS = 18 V).
2 Power Source passive Main power source terminal carrying the drain current; the datasheet gives no separate electrical limit for this pin beyond the 1200 V VDSS and 60 A ratings of the device.
3 Driver Source passive Gate-driver return source terminal, kept separate from the Power Source pin in the datasheet block diagram; the datasheet gives no separate electrical limit for this pin.
4 Gate input Gate input with absolute maximum DC VGS of -10 V / +22 V and recommended operating range of -5 V / +18 V.
