Infineon Technologies’ new CoolSiC diodes are designed for ruggedness and efficiency, to meet the high standards required of hybrid and electric vehicles. Infineon says these diodes are the most durable on the market, due to their high corrosion and humidity resistance. The company will release CoolSiC Diodes in the 650 V class in September.
An improvement on Infineon’s fifth-generation Schottky diodes, the CoolSiC diodes have better figures of merit, and therefore lower power losses. This is due to their 110 µm wafers, which improve overall efficiency. The diodes also improve the efficiency of on-board chargers (OBCs) by one percent compared to other Silicon Rapid diodes, and their 3-pin TO247 package is designed to be easily integrated in each OBC system.
“The SiC technology is now mature enough to be deployed at broad scale in automotive systems,” says Infineon Automotive High Power VP Stephan Zizala. “The launch of the automotive CoolSiC Schottky diode family is a milestone in the deployment of Infineon’s SiC product portfolio for on-board chargers, DC/DC converters and inverter systems.” This development is only part of Infineon’s recent trend of increased research and growth.
