Cmos · MOSFETs · TO-263

CMB18N20A from Cmos, 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; the pin-configuration picture labels the left lead G, with gate-source voltage limited to ±30 V absolute maximum.
2 D passive Drain; the picture labels the drain on the tab, and the middle lead is drawn between G and S. Drain-source voltage is 200 V maximum and continuous drain current is 18 A at Tc=25℃.
3 S passive Source; the picture labels the right lead S, and the body diode is rated 18 A continuous source current.

CAD (KiCad official)

  • Symbol: CMB18N20A
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263 (KiCad packages3D, STEP)
  • 3D model files: cmb18n20a-etched.step / cmb18n20a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmb18n20a.step / cmb18n20a.glb are the bare package body.
