New superjunction MOSFET features an integrated temperature sensor

Infineon Technologies AG releases its new CoolMOS S7T product family with an integrated temperature sensor to enhance the accuracy of junction temperature sensing. The integration of these products positively impacts the durability, safety, and efficiency of many electronic applications. The device is ideal for 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 varied electronic devices, customers can benefit from a superjunction MOSFET with an integrated sensor in the same package. The company's innovative approach improves the relay's performance and provides reliable operation even under overload conditions. The integrated temperature sensor provides up to 40% greater accuracy and ten times faster response time than a standard independent onboard sensor located at the drain. Also, the monitoring process can be performed individually within a multi-device system for improved reliability.

The device allows optimal utilisation 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 solid-state triac solutions are more than five times less efficient. Enhanced efficiency and the ability to handle higher loads help reduce power consumption and energy costs.

Unique output stage performance and a considerable overcurrent threshold bolster relay reliability and minimise the risk of failure and downtime. The rugged switching solution also provides safer operation. As a result of the MOSFET's increased robustness, the life of the relay is enhanced, leading to less frequent replacement. Ultimately, all of these benefits translate into lower maintenance costs.
