3.3 kV SiC Power Devices. New Levels of Efficiency and Reliability

System designers of traction power units (TPUs), auxiliary power units (APUs), solid-state transformers (SSTs), industrial motor drives and energy infrastructure solutions require high-voltage switching technology to increase efficiency, reduce system size and weight and enhance reliability.

Microchip Technology Inc. announced the expansion of its SiC portfolio with the release of the industry’s lowest on-resistance [RDS(on)] 3.3 kV SiC MOSFETs and highest current-rated SiC SBDs available in the market, enabling designers to take advantage of ruggedness, reliability and performance. With the expansion of Microchip’s SiC portfolio, designers are equipped with the tools to develop smaller, lighter and more efficient solutions for electrified transportation, renewable energy, aerospace and industrial applications.

Many silicon-based designs have reached their limits in efficiency improvements, system cost reduction and application innovation. While high-voltage SiC provides a proven alternative to achieve these results, until now, the availability of 3.3 kV SiC power devices was limited. Microchip’s 3.3 kV MOSFETs and SBDs join the company’s comprehensive portfolio of SiC solutions that include 700V, 1200V and 1700V die, discretes, modules and digital gate drivers.

Microchip’s 3.3 kV SiC power devices include MOSFETs with the industry’s lowest RDS(on) of 25 mOhm and SBDs with the industry’s highest current rating of 90 amps. Both MOSFETs and SBDs are available in die or package form (more info).
