Description

The SDT4U40EP3 is a 40-volt 4A trench Schottky barrier rectifier that is optimized for low forward voltage drop and low leakage current, housed in a compact chip scale package (CSP) that occupies only 1.28mm2 board space with low profile. The low thermal resistance enables designers to meet design challenges of increasing efficiency whilst at the same time reducing board space.

Feature(s)

  • Low forward voltage (VF) minimizes conduction losses and
    improves efficiency.
  • Reduced high temperature reverse leakage; Increased reliability
    against thermal runaway failure in high temperature operation.
  • Totally Lead-Free & Fully RoHS Compliant 
  • Halogen and Antimony Free. “Green” Device
  • For automotive applications requiring specific change
    control (i.e. parts qualified to AEC-Q100/101/200, PPAP
    capable, and manufactured in IATF 16949 certified facilities),
    please contact us or your local Diodes representative.
