Alternative Part Number

  • SS16 --: 1A 60V Schottky rectifier in SMA package, a widely available industry-standard equivalent to the SM5817 with similar forward voltage and current rating.
  • MBRA160 --: 1A 60V Schottky diode in SMA case with comparable low forward drop and fast switching, suitable direct replacement for general rectification.
  • B160 --: 1A 60V Schottky barrier rectifier in SMA package, commonly used as a cross for SM5817 in power supply and polarity protection circuits.
  • SS14 --: 1A 40V Schottky diode in SMA package, widely available and directly interchangeable with SM5817 in most rectification and protection circuits.
  • 1N5817 --: Classic 1A 20V Schottky diode with similar forward voltage and current rating, suitable drop-in replacement where through-hole or axial package is acceptable.
  • MBR140 --: 1A 40V Schottky barrier rectifier offering comparable performance and higher voltage margin, a reliable alternative for general-purpose low-voltage rectification.
  • B5817WS --: 1A 20V Schottky diode in SOD-323, closely matches the low-voltage Schottky characteristics of SM5817 with a different series name.
  • MBR120VLSFT1G --: 1A 20V Schottky rectifier in SOD-123FL, comparable forward voltage and current rating, suitable drop-in for low-voltage rectification.
  • SS12 --: 20V/1A Schottky barrier rectifier in SMA/DO-214AC, a common cross-reference for SM5817 with equivalent electrical characteristics.
