Littelfuse extends SiC Schottkys range to 1700V

Littelfuse Inc of Chicago, IL, USA, which provides circuit protection technologies (including fuses, semiconductors, polymers, ceramics, relays and sensors), has expanded its portfolio of silicon carbide (SiC) diodes to include the 1700V-class.

The LSIC2SD170Bxx Series SiC Schottky diodes are available in the TO-247-2L package with a choice of current ratings (10A, 25A or 50A). Offering power electronics system designers a variety of performance advantages, including close-to-zero reverse recovery current, high surge capability and a maximum operating junction temperature of 175°C, they are suitable for applications that require enhanced efficiency, reliability and simplified thermal management.

SiC Schottky barrier diodes are suitable in a wide range of AC/DC and DC/DC power converters for industry, energy generation, and energy distribution/storage, including: industrial switch-mode power supplies; uninterruptable power supplies (UPS); battery chargers; solar inverters; industrial motor drives; and high-speed rectifiers.

“Using SiC diodes in power designs instead of diodes based on legacy silicon-based technology helps designers develop more energy-efficient power converters, saving energy and reducing costs related to cooling the power electronics,” says Francois Perraud, product marketing manager, SiC Products, at Littelfuse. “They enable the design of faster-switching power electronics in the converters which can then be made more compact at the same output power or pack more power in the same volume.”

The LSIC2SD170Bxx SiC Schottky diodes are said to offer the following key benefits:

  • positive temperature coefficient of the forward voltage for safe operation and ease of paralleling;
  • extremely fast temperature-independent switching;
  • dramatically reduced switching losses compared with silicon bipolar diodes and
  • optimized overall system efficiency.

The LSIC2SD170Bxx SiC Schottky diodes are available in the TO-247-2L package, in tube, with a minimum order quantity of 450 devices. Sample requests can be placed through authorized Littelfuse distributors worldwide.
