Application Scenarios & Design Considerations

Ultrafast recovery -1200 V diode

Alternative Part Number

  • BYV34-800 --: 800 V ultrafast recovery diode in TO-220FP-like package with similar current rating, suitable as a direct functional replacement for the STTH812FP in rectification and freewheeling applications.
  • VS-8ETH06FP-M3 --: 600 V hyperfast diode in a fully isolated TO-220FP package, offering comparable forward current and fast recovery behavior for switching power supplies.
  • IDH10G65C5 --: 650 V SiC Schottky diode in TO-220FP with zero reverse recovery, providing a higher-performance upgrade path where switching losses and thermal margin are critical.
