CMDSH-4E TR PBFREE

Central Semicon · Schottky Diodes · SOD-323

CMDSH-4E TR PBFREE from Central Semicon, in a SOD-323. 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 Schottky diode (lead code 1 on the SOD-323 outline), rated for a peak repetitive reverse voltage VRRM of 40 V and an average forward current IO of 200 mA.
2 Anode passive Anode terminal of the Schottky diode (lead code 2 on the SOD-323 outline), with a peak repetitive forward current IFRM of 350 mA and a peak forward surge current IFSM of 750 mA (tp=10 ms).

  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: cmdsh-4e-tr-pbfree-etched.step / cmdsh-4e-tr-pbfree-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmdsh-4e-tr-pbfree.step / cmdsh-4e-tr-pbfree.glb are the bare package body.
