Application Scenarios & Design Considerations

Schottky Barrier Rectifier

Alternative Part Number

  • 1N5819 --: Schottky rectifier with 40V/1A rating; widely available and a common substitute for low-current 40V Schottky applications, though current rating is lower than the SB340A.
  • MBR340 --: 3A 40V Schottky barrier rectifier in a similar axial/DO-201 package, directly comparable in voltage and current class to the SB340A.
  • SR340 --: 3A 40V Schottky rectifier with equivalent ratings and package style, suitable as a drop-in functional replacement for the SB340A.
