Infineon integrates temperature sensor into its CoolMOS S7T

Infineon announced that it has integrated temperature sensor inside its new CoolMOS S7T product family of high-voltage superjunction MOSFETs. Infineon shared these below further details on this announcement: The integration of these products has a positive impact on the durability, safety, and efficiency of many electronic applications. The CoolMOS S7T is best suited for solid-state relay (SSR) applications for enhanced performance and reliability due to its superior R DS(on) and the highly accurate, embedded sensor. Since SSRs are fundamental components in various electronic devices, customers can benefit in many ways from a superjunction MOSFET with an integrated sensor in the same package. Infineon’s innovative approach improves the relay’s performance and ensures reliable operation even under overload conditions. The integrated temperature sensor provides up to 40 percent greater accuracy and ten times faster response time than a standard independent on-board sensor located at the drain. Additionally, the monitoring process can be performed individually within a multi-device system for improved reliability. The CoolMOS S7T enables optimal utilization of the power transistor, resulting in enhanced performance and precise control of the output stage. Compared to electromechanical relays, the total power dissipation can be improved up to two times, while current sol...
