RS100N120T

REASUNOS · MOSFETs · TO-220

RS100N120T from REASUNOS, in a TO-220. 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 MOSFET channel, with VGS limited to ±20 V and a gate threshold of 2 V min to 4 V max at ID=250 µA.
2 D passive Drain (also connected to the mounting tab); rated for VDSS 100 V and continuous drain current of 120 A at TC=25℃, 480 A pulsed.
3 S passive Source; continuous source current through the body diode is 120 A, 480 A pulsed, with a forward diode drop of 1.0 V max at IS=20 A.
