Infineon introduces the new CoolMOS S7T with an integrated temperature sensor

     To improve the accuracy of junction temperature sensing, Infineon Technologies AG introduces the new CoolMOS™ S7T product family with an integrated temperature sensor. By integrating this family of semiconductors into your system, you can improve the durability, safety, and efficiency of many electronic applications. CoolMOS™ S7T features excellent on-resistance and high-precision embedded sensors that are ideal for improving performance and reliability in solid-state relay (SSR) applications.

     SSRS are a basic configuration for a variety of electronic devices, and customers can benefit from the ability to integrate sensors and hyperjunction MOSFETs into the same package. Infineon's innovative solutions improve the performance of relays, enabling them to operate reliably even under overload conditions. The integrated temperature sensor is up to 40% more accurate than a standard standalone onboard sensor located at the drain, has a 10-fold faster response time, and is more reliable because the monitoring process can be performed separately within a multi-device system.

     The CoolMOS™ S7T optimizes the use of power transistors for improved output stage performance and precise control. The reduction in total power dissipation is up to twice that of electromechanical relays, and the efficiency is more than five times higher than current solid-state three-terminal bidirectional thyristor solutions. Increased efficiency and the ability to handle higher loads help reduce power consumption and energy costs.

     Unique output stage performance coupled with significant overcurrent thresholds increases relay reliability and minimizes the risk of failure and downtime. This rugged switching solution also improves operational safety. With greater robustness, MOSFETs extend the service life of relays and reduce replacement frequency. All of these benefits will eventually translate into lower maintenance costs.
