RS100N78T

REASUNOS · MOSFETs · TO-220

RS100N78T 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; gate-to-source voltage limited to ±20 V with a threshold of 1.2 V min to 2.6 V max at 250 µA.
2 D passive Drain (also connected to the mounting tab); drain-to-source voltage 100 V, continuous current 78 A at TC=25℃.
3 S passive Source; connects to the body diode anode, with continuous source current of 78 A.
