Application Scenarios & Design Considerations

Surface Mount Schottky Power Rectifier

Alternative Part Number

  • SS14 --: 1A 40V Schottky rectifier in SMA package, same current/voltage class and footprint as the MBR120ESFT3G, widely available and low cost.
  • B140-E3/61T --: 1A 40V Schottky diode in SMA, direct functional equivalent with similar forward voltage and thermal characteristics.
  • SX34 --: 3A 40V Schottky in SMA, higher current margin than the original 1A part, suitable as a robust drop-in replacement in most designs.
  • 1N5819HW-7-F --: 1A 40V Schottky rectifier in SOD-123, comparable ratings and small surface-mount package suitable for similar board space.
  • B140-13-F --: 1A 40V Schottky barrier rectifier in SMA, direct functional equivalent with matching voltage and current ratings.
