Fast RecoveryRectifierSurface Mount

The U1M is a 1A, 1000V fast recovery diode housed in a compact SOD-123FL surface-mount package, suitable for high-efficiency rectification applications.

Best for

  • General-purpose rectification
  • Fast switching power supplies
  • Surface mount PCB assemblies

Avoid if

  • Applications requiring ultra-low forward voltage drop (Schottky diodes may be better)
  • Extremely high-frequency switching beyond the diode's recovery capability

Check before use

  • Thermal derating based on ambient temperature
  • PCB pad layout dimensions
