650V SiC Schottky diodes in new package sizes reach 40A
Both series offer power electronics system designers a variety of performance advantages over traditional silicon-based devices, including negligible reverse recovery current, high surge capability, and a maximum operating junction temperature of 175°C. This makes them ideal for applications in which improved efficiency, reliability, and thermal management are desirable.
The LSIC2SD065DxxA Series SiC Schottky Diode is available with current ratings of 6A, 10A, or 16A in a TO‑263-2L package; the LSIC2SD065ExxCCA Series SiC Schottky Diode is available with current ratings of 12A, 16A, 20A, or 40A in a TO-247-3L package.
These SiC Schottky Diodes dissipate less energy and can operate at higher junction temperatures than alternative solutions such as standard silicon bipolar power diodes. They also require smaller heat sinks and support a smaller system footprint than those solutions. These advantages offer end-users the benefits of more compact, energy-efficient systems, and a potential lower total cost of ownership.
Typical applications for the diodes include electric vehicle (EV) charging stations, buck/boost stages in DC-DC converters and free-wheeling diodes in inverter stages. They can also be used for high-frequency output rectification and power factor correction (PFC).
“These additions to our fast-growing 650V SiC Schottky Diode family allow us to offer a broader selection of current ratings and package designs suitable for a wider range of applications,” said Christophe Warin, Littelfuse Silicon Carbide Product Marketing Manager at the launch at the APEC 2019 power conference in the US this week. “These new SiC Schottky Diodes enable a variety of design optimization opportunities, including increased power density, higher efficiency and potentially lower bill of materials costs.”
The LSIC2SD065DxxA Series SiC Schottky Diodes are available in TO-263-2L packaging and LSIC2SD065ExxCCA Series SiC Schottky Diodes are available in TO-247-3L packaging. Both in tape and reel format, with a minimum order quantity of 800 devices. Sample requests may be placed through authorized Littelfuse distributors worldwide.
