MPF18N50

miracle · MOSFETs · TO-220F

MPF18N50 from miracle, in a TO-220F. 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 control input with a gate-source voltage rating of ±30 V and a threshold of 2 V to 4 V at VDS = VGS, ID = 250 µA.
2 D passive Drain terminal with a drain-source voltage rating of 500 V and continuous drain current of 18 A at TC = 25°C (72 A pulsed).
3 S passive Source terminal and current return path, carrying up to 18 A continuous at TC = 25°C.
