CSD18537NKCS-VB

VBsemi Elec · MOSFETs · TO-220AB

CSD18537NKCS-VB from VBsemi Elec, in a TO-220AB. 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-source voltage limited to ±20 V, with RDS(on) specified at VGS = 10 V and 4.5 V.
2 D passive Drain (also connected to the tab); 60 V drain-source rating, 60 A continuous at TC = 25 °C and 200 A pulsed.
3 S passive Source; continuous source (diode) current 50 A, package limited.
