KCMSH3-40MA

KUU · Schottky Barrier Diodes (SBD) · SMA

KCMSH3-40MA from KUU, in a SMA. 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 Cathode passive Cathode terminal of the Surface Mount Schottky Barrier Rectifier (PINNING table, top view of SMA outline); the device is rated for VRRM 40 V and IF(AV) 3.0 A.
2 Anode passive Anode terminal of the Surface Mount Schottky Barrier Rectifier (PINNING table, top view of SMA outline), forming the forward-conduction path to the cathode at pin 1.

CAD (KiCad official)

  • Symbol: KCMSH3-40MA
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: kcmsh3-40ma-etched.step / kcmsh3-40ma-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kcmsh3-40ma.step / kcmsh3-40ma.glb are the bare package body.
