MOSFET Integrates Temperature Sensor for Enhanced Functionality

Infineon Technologies has introduced a groundbreaking 600V Superjunction MOSFET, the CoolMOS S7TA, featuring an integrated temperature sensor tailored for automotive power management applications. This cutting-edge technology is designed to cater to the specific demands of automotive electronics, enhancing accuracy in junction temperature sensing with the inclusion of a temperature sensor within the package.

The CoolMOS S7TA builds upon the success of its industrial counterpart, the CoolMOS S7T, by offering improved reliability and durability. Particularly well-suited for solid-state relay (SSR) applications, this innovative MOSFET showcases superior RDS(on) and sensing accuracy, essential for efficient power management solutions in various automotive electronic devices.

The integration of a Superjunction MOSFET with an embedded temperature sensor within the same package elevates the performance of SSRs, ensuring dependable operation even under extreme overload conditions. The embedded sensor in the S7TA model boasts a 40% increase in accuracy and up to four times faster response time compared to standalone on-board sensors, marking a significant advancement in temperature monitoring critical for automotive applications.

One of the key benefits of the CoolMOS S7TA is its ability to enhance Zero Voltage Switching (ZVS) performance, achieved through precise control of the output stage. This level of precision plays a crucial role in reducing power consumption and energy costs, addressing the growing need for efficiency in automotive applications where improved performance directly impacts vehicle range and operational economy.

Furthermore, the CoolMOS S7TA offers a high overcurrent threshold, enhancing the reliability of SSRs and reducing the risk of failures. This robust switching solution not only ensures safer operations within vehicles but also extends the lifecycle of automotive relays, resulting in reduced maintenance and replacement expenses.
