STPOWER IH2 devices target industrial and induction-heating applications
Geneva, Switzerland – WEBWIRE – Monday, September 4, 2023
Geneva, Switzerland, September 4, 2023 STMicroelectronics has released a new class of IGBTs with an increased breakdown-voltage capability of 1350V and maximum operating temperature of 175C. The higher ratings ensure greater design margin, robust performance, and extended reliability under all operating conditions.
The new STPOWER IH2 series IGBTs also permit increased 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 16kHz to 60kHz.
With their ruggedness and high efficiency, these IGBTs are ideal for induction-heating applications including domestic appliances such as kitchen hobs, inverter microwave ovens, and rice cookers. In a 2kW application, STs new IGBT devices can reduce power dissipation by up to 11%.
In addition, the Vce(sat) has a positive temperature coefficient and tight parameter distribution between devices helps simplify design and ease connecting multiple IGBTs in parallel to address high-power applications.
The first two devices in the series, the 25A STGWA25IH135DF2 and 35A STGWA35IH135DF2, are in production now and available in a standard TO-247 long-lead power package. Pricing starts from $1.39 for the STGWA25IH135DF2 and $1.69 for the STGWA35IH135DF2, for orders of 1000 pieces.
