GEN2 650V SiC Schottky Diodes Offer Improved Efficiency, Reliability and Thermal Management

Littelfuse LSIC2SD065CxxA LSIC2SD065AxxA

Negligible reverse recovery current, high surge capability, and 175 °C max. operating junction temperature

Littelfuse introduced two second-generation series of 650 V, AEC-Q101-qualified silicon carbide (SiC) Schottky Diodes. The LSIC2SD065CxxA and LSIC2SD065AxxA Series SiC Schottky Diodes are available with a choice of current ratings (6 A, 8 A, 10 A, 16 A or 20 A). 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 ideal for applications that require enhanced efficiency, reliability, and thermal management.

When compared to standard silicon PN-junction diodes, the 650 V Series SiC Schottky Diodes support dramatic 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 650 V 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.

The 650 V Series SiC Schottky Diodes offer these key benefits:

  • AEC-Q101-qualified diodes exhibit exceptional performance in demanding applications.
     
  • Far lower switching losses than silicon bipolar diodes and fast, temperature-independent switching behavior make these devices suitable for high-frequency power switching.
     
  • The positive temperature coefficient enables safe operation and ease of paralleling.
     
  • The 175 °C maximum operating junction temperature provides a larger design margin and relaxed thermal management requirements.
