SP40N03BTD

Siliup · MOSFETs · TO-263

SP40N03BTD from Siliup, in a TO-263. 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 terminal; gate-source voltage VGSS is rated at ±20 V per the absolute maximum ratings.
2 D passive Drain terminal; the device is rated for 40 V drain-source voltage (VDSS) and 130 A continuous drain current at Tc=25°C.
3 S passive Source terminal; maximum body-diode continuous current IS is rated at 130 A.
