Mitsubishi Electric Corporation announced that the company is poised to launch a new series of silicon-carbide metal-oxide-semiconductor field-effect transistors (MOSFETs), the N-series of 1200V SiC-MOSFETs in a TO-247-4 (4-terminal) package, which achieves 30% less switching loss compared to the existing TO-247-3 package products.
N-series 1200V SiC-MOSFETs
The new 4-terminal N-series 1200V SiC-MOSFETs will help to reduce the power consumption and physical size of power supply systems that require high-voltage conversion, such as electric vehicle (EV) on-board chargers and photovoltaic power systems. Sample shipments will start in November 2020.
Product features include:
- Four-pin package helps reduce power consumption and physical size of power-supply systems - SiC-MOSFET chip with good figure of merit (FOM3) of 1,450mΩ-nC and high self-turn-on tolerance is mounted on TO-247-4 package, which is equipped with independent driver source terminal as well as conventional 3-pin package.
- Adopts four-pin package to reduce parasitic inductance, a problem in high-speed switching - Eliminating gate-source voltage drops due to current variations helps to reduce switching loss by approximately 30% compared with TO-247-3 products.
- Using a higher carrier frequency to drive the new power semiconductors helps to reduce switching-power loss, enabling smaller and simpler cooling systems, as well as smaller reactors and other peripheral components, thereby helping to reduce the power consumption and physical size of overall power-supply systems.
- Six models for diverse applications, including AEC-Q101 compliant models - New lineup includes models compatible with Automotive Electronics Council's AEC-Q101 standards for use not only in industrial applications, e.g. photovoltaic systems, but also EV applications.
- Creepage distance (shortest distance over the surface between two conductive parts) between drain terminal and source terminal made wider than in TO-247-3 package products for more flexible application, including in outdoor installations where dust and dirt easily accumulate.
