SiC肖特基二极管

SiCショットキバリアダイオード

Toshiba offers a wide range of 2nd Gen.650-V silicon carbide Schottky barrier diodes (SiC SBDs) with a rated current of 2 A to 10 A, in through-hole (TO-220) packages.
The 2nd Gen.SiC SBD series provides a 30% lower figure of merit (VF*QC)*1 and a higher surge peak forward current (IFSM) than the 1st Gen.SiC SBD series and therefore helps improve the efficiency and reduce the size of power supplies.

Introduction

  • High surge forward current (IFSM): Approximately 7 to 9 times of current rating IF(DC)
  • Figure of Merit  (VF・Qc[Note 1]): Approximately 30% reduction compared to the 1st generation devices, realizing higher efficiency
  • Various package lineup including isolated type and surface mount type:suit various design requirements

Purpose

SiC SBDs are suitable for power factor correction (PFC) circuits in high-efficiency power supplies, chopper circuits, and freewheel diodes integrated in switching devices.

  • Consumer electronics and office equipment: 4K LCD TVs, projectors, multifunction copiers, etc.
  • Industrial equipment: Communication base stations, PC servers, etc.
  • AC-DC Power Supplies
  • DC-DC Power Supplies

*1  VF・QC  : The product of forward voltage and total charge (VF*QC) indicates the loss performance of SiC Schottky barrier diodes. When devices with the same current rating are compared, a device with a lower VF*QC provides a lower loss.
