Alternative Part Number

  • MBR0520L --: Schottky barrier diode with similar low forward voltage and current rating, commonly used as a drop-in replacement in low-power rectification.
  • BAT54 --: Small-signal Schottky diode with comparable switching characteristics and low Vf, suitable for signal-level and clamping applications.
  • 1N5819 --: Widely available Schottky rectifier with similar voltage/current class, easy to source and often used where MB15C03 is specified.
  • SBR10U40CT --: Schottky barrier rectifier with similar 10A/40V rating and low forward voltage, suitable drop-in replacement for MB15C03 in most rectification circuits.
  • MBR1040 --: 10A 40V Schottky diode with comparable current and voltage ratings, widely available and electrically similar to the original part.
  • STPS1040 --: 10A 40V Schottky rectifier offering similar forward voltage and thermal performance, usable as an alternative with minor layout considerations.
