    First full-SiC-Module Bulk Production Started by Infineon

    Higher efficiency, increased power density, smaller footprints and reduced system costs: these are the main advantages of transistors based on silicon carbide (SiC). Infineon Technologies AG  is starting volume production for the EASY 1B, the first full-SiC module announced during PCIM 2016. On the occasion of this year’s PCIM in Nuremberg, the company is showcasing additional module platforms and topologies for the 1200 V CoolSiC MOSFET family. Infineon is now able to bring the potential of SiC technology to a new level.

    “Silicon carbide has reached a tipping point: Taking cost-benefit analysis into account, it is ready for use in a variety of applications,” said Dr. Peter Wawer, Division President Industrial Power Control from Infineon. “In order to make the new semiconductor technology a revolution to rely on, however, it needs a partner like Infineon. Products tailored to the application, our own production capacities, comprehensive technology portfolio and system understanding: these four building blocks have made us the market leader for power semiconductors. We want and will also achieve this with our SiC product portfolio.”

    The new 1200 V SiC MOSFETs have been optimized to combine high reliability with performance. They show dynamic losses which are an order of magnitude lower than 1200 V silicon (Si) IGBTs. First products will initially support upcoming system challenges in applications such as photovoltaic inverters, uninterruptible power supplies (UPS) and charging/storage systems. The new configurations will also enable revolutionary new solutions in industrial drives, medical technology or auxiliary power supplies in the railway sector in the near future.

    One major advantage of the trench technology with the 1200 V SiC MOSEFT lies in an extended robustness. This is due to the lower failure in time (FIT) rate and the short-circuit capability, which can be adapted to the respective application. Thanks to a threshold voltage (Vth) of 4 V and the recommended switch-on threshold (VGS) of +15 V, the transistors can be controlled like an IGBT and safely switched off in the event of a fault. The SiC MOSFETs enable very fast switching transients. In addition, Infineon’s technology offers an easy adjustability of the transients via gate series resistors. The EMC behavior can thus be easily optimized.
