CMU6780A

Cmos · MOSFETs · TO-251

CMU6780A from Cmos, in a TO-251. 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 channel, with VGS rated ±20 V maximum and threshold of 1 V to 3 V at 250 µA.
2 D passive Drain; rated 30 V VDS with 50 A continuous and 150 A pulsed drain current, also connected to the tab.
3 S passive Source; main current return of the N-channel MOSFET, with 50 A continuous source current.

CAD (KiCad official)

  • Symbol: CMU6780A
  • Footprint: Package_TO_SOT_THT:TO-251-3_Vertical
  • 3D model: TO-251 (KiCad packages3D, STEP)
  • 3D model files: cmu6780a-etched.step / cmu6780a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmu6780a.step / cmu6780a.glb are the bare package body.
