Mitsubishi Electric Corporation has reportedly shared plans to introduce a new series of silicon carbide MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) called the N-series of 1200V SiC-MOSFETs in a TO-247-4 package. These transistors have been designed for securing 30 per cent less switching loss against the company’s current TO-247-3 package products.
The new series will reportedly facilitate the reduction of power consumption along with physical size of power-supply systems that demand high-voltage conversion, for instance, photovoltaic power systems and EV (electric vehicle) on-board chargers. Sample shipments of this package are set to begin this November, added sources.
Mitsubishi’s new series effectively comes in six different models for various applications. The company’s new product suite comprises models that depict compatibility with Automotive Electronics Council’s AEC Q101 standards for utilization in both, industrial applications such as photovoltaic systems as well as in electric vehicle applications.
The new product, further, has a wider creepage distance between the source terminal and drain terminal as compared to the company’s TO-247-3 package products for providing flexible application, in outdoor installations as well where dirt and dust get easily accumulated.
Also, a SiC-MOSFET chip having a high self-turn-on tolerance and a good figure of merit of 1,450m-n has been mounted on the TO-247-4 package, equipped with conventional 3-pin package and an independent driver source terminal. The deployment of a higher carrier frequency for driving the new power semiconductors helps in the reduction of switching-power loss, allowing simpler and smaller cooling systems, in turn facilitating the reduction of power consumption and the physical size of the overall power-supply systems.
