Infineon Technologies (Korea CEO Seung-soo Lee) announced on the 14th that it is launching the new CoolMOS™ S7T product family.

The CoolMOS S7T product family, which integrates temperature sensors to improve junction temperature detection accuracy, has a positive impact on the durability, safety, and efficiency of many electronic applications.

The CoolMOS S7T improves the performance and reliability of solid-state relay (SSR) applications thanks to its excellent RDS(on) and high-precision built-in sensor.

Since SSRs are fundamental components of various electronic devices, superjunction MOSFETs that integrate sensors into the same package offer many advantages.

Infineon's innovative approach enhances relay performance and ensures stable operation even under overload conditions.

The integrated temperature sensor has up to 40 percent higher accuracy and a 10 times faster response time compared to a standard independent onboard sensor located at the drain.

In addition, monitoring can be performed individually to improve reliability in multi-device systems.

The CoolMOS S7T achieves enhanced performance by optimally utilizing power transistors and enables precise control of the output stage. Improved efficiency and the ability to handle higher loads help reduce power consumption and energy costs.

The combination of unique output stage performance and a high overcurrent threshold enhances relay reliability and minimizes the risk of failure and downtime. In addition, the robust switching solution ensures safer operation.

The high robustness of MOSFETs extends relay life. This reduces the frequency of component replacement, ultimately leading to lower maintenance costs.

Engineering samples and start kits for the TOLL package CoolMOS S7T will be available starting February 2024.
