This diode is commonly used in power supplies, inverters, and motor control circuits.

Application Scenarios & Design Considerations

Ultrafast recovery - 1200 V diode

Alternative Part Number

  • VS-15ETH12-M3 --: Hyperfast 15 A, 1200 V TO-247/TO-220 diode with similar forward current and blocking voltage, suitable drop-in replacement for high-frequency rectification.
  • IDH15S120 --: 15 A, 1200 V SiC Schottky diode in TO-220, offers lower switching losses and comparable ratings for the same application.
  • DSEI12-12A --: 12 A, 1200 V fast recovery epitaxial diode in TO-220, close electrical match with slightly lower current rating but widely available.
