RS20N50W

REASUNOS · MOSFETs · TO-247

RS20N50W from REASUNOS, in a TO-247. 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; controls the channel, with VGS limited to ±30 V and a threshold of 3 to 4 V at ID=250µA.
2 D passive Drain; rated for 500 V drain-to-source and 20 A continuous current at TC=25℃ (80 A pulsed), and connected to the mounting tab.
3 S passive Source; the current return path for the 20 A drain current, with the body diode in parallel from source to drain.
