Application Scenarios & Design Considerations

Conductor Holdings Limited - SURFACE MOUNT SCHOTTKY BARRIER RECTIFIERS

Alternative Part Number

  • 1N5819 --: Schottky diode with 40V/1A rating, widely available and a common substitute for MBRX140 in similar low-voltage rectification applications.
  • SS14 --: 1A 40V Schottky rectifier in SMA package, electrically comparable and easy to source as a drop-in alternative.
  • BAT54 --: Small-signal Schottky diode suitable for low-current 40V applications, useful when board space is limited and current demand is modest.
  • SB140 --: 1A 40V Schottky barrier diode in DO-41 package, directly comparable ratings and footprint to the MBRX140.
