Wolfspeed’s new line of 650V SiC MOSFETS, which incorporate the latest third-generation C3M silicon carbide (SiC) technology, join its established family of industry-leading sixth-generation C6D Schottky diodes, to deliver today’s design engineer exceptional performance, reliability, and efficiency.

The many advantages of silicon carbide

Wolfspeed Silicon Carbide wide-bandgap semiconductors outperform conventional silicon (Si) components and set new standards for efficiency and reliability in application areas across several industry verticals, including automotive and transportation, industrial, renewable energy, test and measurement, aerospace, and more.

Compared to traditional materials like silicon and even gallium nitride (GaN), Silicon Carbide has higher thermal conductivity and significantly lower losses. And while other materials must scale more quickly to handle higher voltages (leading to increased size and costs), Silicon Carbide is the epitome of “doing more with less” — keeping size, weight, and costs down. Silicon Carbide also offers avalanche ruggedness to avoid catastrophic failures and maintain its high reliability even in overstress conditions.

Peak performance with Wolfspeed

Wolfspeed’s 650V SiC MOSFETs and Schottky diodes are the result of years of research and development into building the highest-performing Silicon Carbide semiconductors in the industry. Wolfspeed Silicon Carbide products enable the lowest conduction losses in the industry and provide fast switching speeds with low losses that reduce the size of external components.

A closer look at Wolfspeed’s 650V SiC MOSFETs and Diodes

Wolfspeed’s 650V SiC MOSFETs and Diodes can withstand even the most demanding of applications. When you compare Wolfspeed solutions to other offerings on the market — well, there simply is no comparison:
