Bridge Rectifiers

bridge rectifier4 A1000 VD3Kthrough-holeglass passivated

UD4KB100 is a 4 A, 1000 V D3K bridge rectifier for single-phase AC-to-DC conversion where through-hole mounting and high reverse-voltage capability are required.

Best for

  • Single-phase AC rectification
  • Through-hole power-supply front ends
  • General-purpose high-voltage rectification

Avoid if

  • Surface-mount assembly is required
  • A verified lifecycle status is mandatory
  • Load or thermal conditions exceed the datasheet ratings

Check before use

  • Confirm the 1000 V reverse-voltage rating covers system transients.
  • Calculate bridge losses and junction temperature at the actual load current.
  • Verify pin 1 is output anode (+), pins 2 and 3 are AC inputs (~), and pin 4 is output cathode (-).
