600 V CoolMOS™ S7A / S7TA
The 600 V CoolMOS™ S7A high-voltage superjunction MOSFET family delivers the best performance for low-frequency switching applications at the best price
The CoolMOS™ S7A family stands as a significant advancement resulting from the successful technical optimization of the renowned CoolMOS™ 7 technology, tailored for low frequency switching applications by eliminating redundant features related to switching performance. This technology maintains a cost-optimized design without compromising quality or performance, while reaching very low RDS(on) values. Additionally it is crafted to exceed the highest automotive quality standards, including the AEC-Q101 standard.
The CoolMOS™ S7TA product family is a new variant of the CoolMOS™ S7A, designed to meet the specific requirements of automotive power management applications. It features an integrated temperature sensor that significantly improves the accuracy of junction temperature sensing
The integration of these features has a positive impact on the durability, safety, and efficiency of many electronic applications. The resulting benefits include improved durability, safety, and efficiency, all of which are essential in the automotive domain.
Like its S7A counterpart, the CoolMOS™ S7TA product family is particularly well suited for applications, such as HV eFuse, HV eDisconnect, and on-board chargers, demonstrating superior RDS(on) and sensing accuracy, which is crucial for various automotive electronic devices that rely on efficient power management solutions. The integration of a superjunction MOSFET with an embedded temperature sensor in the same package enhances the performance of SSRs and ensures dependable operation even under the most severe overload conditions, which is an absolute necessity for automotive applications where reliability is non-negotiable.

CoolMOS™ S7A is the semiconductor solution for HV eDisconnect and HV eFuse. It answers eMobility needs with respect to reliability (maintenance-free), flexible and cost optimized system integration, scalability and minimized failure propagation.
CoolMOS™ S7A can bring clear benefits in on-board charger PFC stage. An efficiency improvement of +0.5% and a reduction in power losses of -30% can be achieved in a classic boost PFC topology by replacing the diode bridge with the S7A in an ALR (active line rectification) configuration.
Q-DPAK top-side cooled innovative technology allows for bigger chip implementations reaching the lowest RDS(on) in the market in an SMD. Thanks to its built-in 4th pin Kelvin source configuration and low parasitic source inductance, switching losses are minimized while controllability and ease of use are increased. The cooling concept it offers, enables the thermal decoupling of board and semiconductor. This way, higher chip temperatures are possible and system designers can benefit from the increased flexibility in the PCB design.
