Infineon Launches Automotive CoolSiC Schottky Diodes at 2018 PCIM

The first products of Infineon’s automotive Silicon Carbide portfolio: the CoolSiC Schottky diode family is ideal for current and future on-board charger (OBC) applications in hybrid and electric vehicles. Infineon designed the diodes specifically to meet the high requirements of the automotive industry regarding reliability, quality and performance.

Infineon Technologies presented the first products of its automotive Silicon Carbide portfolio: the CoolSiC Schottky diode family at this year’s PCIM Europe trade fair in Nuremberg-which is now ready for current and future on-board charger (OBC) applications in hybrid and electric vehicles. Infineon designed the diodes specifically to meet the high requirements of the automotive industry regarding reliability, quality, and performance.

“The SiC technology is now mature to be deployed at broad scale in automotive systems“, said Stephan Zizala, Vice President and General Manager for Automotive High Power at Infineon. “The launch of the automotive CoolSiC Schottky diode family is a milestone in the deployment of Infineon’s SiC product portfolio for the onboard charger, DC/DC converters, and inverter systems”.

The new product family is based on Infineon’s 5th generation Schottky Diode, which has been further optimized to meet the reliability requirements demanded by the automotive industry. Thanks to a new passivation layer concept, this is the most robust automotive device available in the market regarding humidity and corrosion. Moreover, because it is based on a 110µm thin wafer technology, it shows one of the best figures of merit (Qc x Vf) in its category. A lower figure of merit implies lower power losses and therefore a better electrical performance.

Compared to the traditional Silicon Rapid diode, the CoolSiC Automotive Schottky Diode can improve the efficiency of an OBC by one percentage point overall load conditions. This leads to a potential reduction of 200kg of CO 2 emissions over the typical lifetime of an electric car, based on the German energy mix.

The first derivate will be available for the open market in September 2018 in the 650V class. Using a standard 3-pinTO247 package, the new products can easily be implemented in an OBC system. They can optimally be used in combination with Infineon’s TRENCHSTOP IGBT and CoolMOS products.
