Littelfuse unveils GEN2 650V SiC Schottky diodes

Littelfuse has introduced two second-generation series of 650V, AEC-Q101-qualified silicon carbide (SiC) Schottky diodes.

The LSIC2SD065CxxA and LSIC2SD065AxxA Series SiC Schottky Diodes are available with a choice of current ratings (6A, 8A, 10A, 16A or 20A). They offer power electronics system designers a variety of performance advantages, including negligible reverse recovery current, high surge capability, and a maximum operating junction temperature of 175°C, so they are suitable for applications that require enhanced efficiency, reliability, and thermal management.

The 650V Series SiC Schottky Diodes support significant reductions in switching losses and substantial increases in the efficiency and robustness of a power electronics system.

Because they dissipate less energy and can operate at higher junction temperatures than Si-based solutions, they allow for smaller heat sinks and a smaller system footprint. This provides end-users with all the advantages of more compact, energy-efficient systems and the potential for a lower total cost of ownership.

Typical applications for 650V Series SiC Schottky Diodes include:

  • power factor correction (PFC),
  • buck/boost stages in DC-DC converters,
  • free-wheeling diodes in inverter stages,
  • high-frequency output rectification and
  • electric vehicle (EV) applications.
