STMicroelectronics has launched a new class of IGBTs with higher breakdown voltage capability of 1350V and maximum operating temperature of 175°C. Higher ratings ensure greater design margin, robust performance and extended reliability under all operating conditions.
The new STPOWER IH2 series IGBTs also enable greater power conversion efficiency. Favorable parameters include low saturation voltage, Vce(sat), which ensures low dissipation when the device is turned on.
The freewheeling diode has low voltage drop and optimized turn-off energy that increases the efficiency of single-switch quasi-resonant converters operating at frequencies from 16k to 60kHz.
With their robustness and high efficiency, these IGBTs are ideal for induction heating applications, including household appliances such as kitchen stoves, inverter microwave ovens and rice cookers. In a 2kW application, ST's new IGBT devices can reduce power dissipation by up to 11%.
Furthermore, Vce(sat) has a positive temperature coefficient and an accurate distribution of parameters between devices helps simplify the design and facilitates the connection of multiple IGBTs in parallel to meet high power applications.
