Description and Applications
The SDM1U40CSP is a 40-volt 1A Schottky Barrier Rectifier that is
optimized for low forward voltage drop and low leakage current.
Housed in a compact chip scale package (CSP), the SDM1U40SCP
occupies only 0.84 mm2 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. It is ideally
suited for use in portable applications as a:
Blocking Diode
Boost Diode
Switching Diode
Reverse Protection Diode

Features and Benefits
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 (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
