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
