Alternative Part Number

  • DB3X314J0L --: Schottky barrier diode in a similar small surface-mount package with comparable forward current and low VF, suitable as a direct functional replacement.
  • BAT54 --: Common small-signal Schottky diode with similar current rating and low forward voltage, widely available and pin-compatible in SOT-23 designs.
  • 1N5819 --: Schottky diode with higher current capability and similar low forward drop; usable where board space allows and slightly higher ratings are acceptable.
  • DB3S314A0L --: Schottky barrier diode in a similar small-signal package with comparable forward voltage and current ratings, suitable as a direct functional replacement.
  • BAT54A --: Common small-signal Schottky diode with low forward voltage drop, widely available and electrically similar for general switching and clamping applications.
  • 1N5711 --: Small-signal Schottky diode with low capacitance and fast switching, usable as an alternative where the MA143A is used for signal detection or protection.
