Infineon Technologies AG launches its new CoolMOS™ S7T product family with an integrated temperature sensor to improve the accuracy of junction temperature sensing. The integration of these products has a positive impact on the durability, safety, and efficiency of many electronic applications. The CoolMOS S7T is best suited for solid-state relay (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 various electronic devices, customers can benefit in many ways from a superjunction MOSFET with an integrated sensor in the same package. Infineon’s innovative approach improves the relay’s performance and ensures reliable operation even under overload conditions. The integrated temperature sensor provides up to 40 percent greater accuracy and ten times faster response time than a standard independent on-board sensor located at the drain. Additionally, the monitoring process can be performed individually within a multi-device system for improved reliability.
The CoolMOS S7T enables optimal utilization 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 5 times less efficient. Improved efficiency and the ability to handle higher loads help in reducing power consumption and energy costs.
Unique output stage performance, coupled with a significant overcurrent threshold, bolster relay reliability and minimizes the risk of failure and downtime. The rugged switching solution also ensures safer operation. As a result of the MOSFETs increased robustness, the life of the relay is improved, leading to less frequent replacement. Ultimately, all of these benefits translate into lower maintenance costs.

Intelligent management of power loads and power sources can make existing power networks more robust in order to handle the growing share of green energy. At the conclusion of the PROGRESSUS research project 22 project partners presented the project’s results in Bari, Italy.
Among other things, a solution was introduced which would make it possible to operate ten to fifteen times more electric car charging stations on a single network connection. In addition, a strategy for tracking electricity from generation all the way to consumption was presented. PROGRESSUS focused on three central topics: Efficient energy conversion, intelligent electricity management and secure network monitoring.
The Electronic Components and Systems for European Leadership Joint Undertaking (ECSEL-JU) and the governments of Germany, Italy, the Netherlands, Slovakia and Spain supported PROGRESSUS with almost 20 million euros. A total of 22 project partners from industry and research participated beginning on 1 April 2020; the project was led by Infineon Technologies AG.
“Decarbonization and electrification go hand in hand. Our power grids will have to perform better and become more stable if they are to handle the growing power volumes and fluctuations in the supply and demand of electricity. This means we need new solutions,” said Thomas Zollver, Senior Vice President Technology & Innovation of the Infineon Connected Secure Systems division.
“The joint research project PROGRESSUS has succeeded in developing a significant number of technologies that can make our existing networks more resilient. The project is thus making an important contribution to freeing our modern lives from fossil energy sources and protecting our climate for future generations.”
The project developed highly efficient electric power converters what minimizes loss while integrating battery storage systems and renewable energy sources such as photovoltaics: The converters integrate ultra-fast sensors and SiC MOSFETs which can be switched at considerably higher speeds.
This makes them suitable for use in new, innovative charge management systems for battery-electric vehicles which reduce the peak power consumption at the site level by as much as 90 percent, without significantly longer charging times. As an alternative the intelligent charging algorithm can support ten to fifteen times more charging stations on the same network connection.
Hardware-based security solutions provide the best possible protection of the communications and data in the power network’s critical infrastructure against manipulation. These solutions also serve as a basis for tracking the energy provided from the point of generation all the way to its consumption. This makes it possible for consumers to prove they are using green electricity.
Joint energy management of multiple buildings can also help relieve power networks. PROGRESSUS project partners have simulated this kind of energy management system based on real data from 16 buildings with photovoltaic systems and energy storage systems. The result: This kind of joint energy management could reduce electricity peak demands present in the public network by an average up to 80 percent, without a negative impact on customers’ needs. This value for the case investigated depends on the season, weather conditions and the configuration of the PV and storage systems.
The findings of the PROGRESSUS project constitute an important contribution to the new products and services which support the achievement of European climate targets.

The accelerated transition to electric vehicles has led to significant innovations in charging systems that demand more cost-efficient and high performing power electronics. Addressing this, Infineon Technologies AG expands its 650 V CoolMOS™ CFD7A portfolio by introducing the QDPAK package.
This package family is designed to provide equivalent thermal capabilities with improved electrical performance over the well-known TO247 THD devices, thus enabling efficient energy utilization in onboard chargers and DC-DC converters.
Efficient and powerful electric vehicle charging systems help reduce charging times and vehicle weight, increasing design flexibility and reduce the total cost of ownership of the vehicle. This new addition complements the existing CoolMOS CFD7A series, offering versatility with top-side and bottom-side cooled packages. The QDPAK TSC (top side cooled), enables designers to achieve higher power densities and optimal PCB space utilization.
The 650 V CoolMOS CFD7A offers several important features for reliable operation in high-voltage applications. Thanks to its reduced parasitic source inductance, the device can minimize electromagnetic interference (EMI), ensuring clear signals and consistent performance.
The Kelvin source pin also provides improved precision for current sensing, ensuring accurate measurements even in challenging conditions. With a creepage distance suitable for high voltage applications, as well as high current capability and high power dissipation (P tot) of up to 694 W at 25°C, it is a versatile and powerful device for a wide range of high-voltage applications.
New system designs using 650 V CoolMOS CFD7A in QDPAK TSC will maximize PCB space use, doubling power density and enhancing thermal management via substrate thermal decoupling. This approach simplifies assembly, eliminates board stacking and reduces the need for connectors, thereby lowering system costs. The power switch reduces thermal resistance by up to 35 percent, providing high power dissipation that outperforms standard cooling solutions.
This feature overcomes the thermal limitations of bottom side cooled SMD designs using FR4 PCBs, resulting in a significant boost in system performance. The optimized power loop design locates drivers near the power switch, improving reliability by reducing stray inductance and chip temperatures. Overall, these features contribute to a cost-effective, robust, and efficient system ideal for modern power needs.
As announced in February 2023, the QDPAK TSC package has been registered as a JEDEC standard for high-power applications, helping to establish a broad adoption of TSC in new designs with one standard package design and footprint. To further to accelerate this transition, Infineon will also release additional Automotive Qualified devices in QDPAK TSC for onboard chargers and DC-DC converters in 2024, such as 750 V and 1200 V CoolSiC™ devices.

Infineon Technologies AG announced the expansion of its CoolSiC 1200 V and 2000 V MOSFET module families with a new industry-standard package. The proven 62mm device is designed in half-bridge topology and is based on the recently introduced and advanced M1H silicon carbide (SiC) MOSFET technology.
The package enables the use of SiC for mid-power applications from 250 kW – where silicon reaches the limits of power density with IGBT technology. Compared to a 62mm IGBT module, the list of applications now additionally includes solar, server, energy storage, EV charger, traction, commercial induction cooking and power conversion systems.
The M1H technology enables a significantly wider gate voltage window, ensuring high robustness to driver and layout-induced voltage spikes at the gate without any restrictions even at high switching frequencies. In addition to that, very low switching and transmission losses minimize cooling requirements.
Combined with a high reverse voltage, these devices meet another requirement of modern system design. By using Infineon’s CoolSiC chip technology, converter designs can be made more efficient, the nominal power per inverter can be increased and system costs can be reduced.
With baseplate and screw connections, the package features a very rugged mechanical design optimized for highest system availability, minimum service costs and downtime losses. Outstanding reliability is achieved through high thermal cycling capability and a continuous operating temperature (T vjop) of 150°C. The symmetrical internal package design provides identical switching conditions for the upper and lower switches. Optionally, the thermal performance of the module can be further enhanced with pre-applied thermal interface material (TIM).
The CoolSiC 62mm package MOSFETs are available in 1200 V variants of 5 mΩ/180 A, 2 mΩ/420 A and 1 mΩ/560 A. The 2000 V portfolio will include the 4 mΩ/300 A and 3 mΩ/400 A variants. The portfolio will be completed in Q1 2024 with the 1200 V/3 mΩ and 2000 V/5 mΩ variants.
An evaluation board is available for rapid characterization of the modules (double pulse/continuous operation). For ease of use, it provides flexible adjustment of the gate voltage and gate resistors. At the same time, it can be used as a reference design for driver boards for volume production.
