Infineon introduces new Solid-State Isolators to deliver faster switching with up to 70 percent lower power dissipation

Munich, Germany, and Long Beach, California - 28 February 2024 – Today at the Applied Power Electronics Conference (APEC), Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) introduced a new product family of Solid-State Isolators to achieve faster and more reliable circuit switching with protection features not available in optical-based solid state relays (SSR). The isolators use coreless transformer technology and support 20 times greater energy transfer with both current and temperature protection contributing to a higher reliability and lower cost of ownership. The new solid-state isolators allow driving the gates of Infineon’s MOS-controlled power transistors OptiMOS ^™ and CoolMOS™ to reduce power dissipation of up to 70 percent of todays’ solid-state relays using SCR (silicon-controlled rectifier) and Triac switches.

Infineon's solid-state isolators enable custom solid-state relays capable of controlling loads more than 1000 V and 100 A. Improved performance and reliability make coreless transformer technology ideal for applications in advanced battery management, energy storage, renewable energy systems, as well as industrial and building automation system applications. With Infineon’s solid-state isolator drivers, engineers can further improve the efficiency of electronic and electromechanical systems.  

“Implementing coreless transformers in solid-state isolators and relays is truly a game-changer for power engineers; it provides 50 times lower RDS _(on) than existing optically controlled solutions. This enables their use in higher-voltage and higher power applications,” said Davide Giacomini, Marketing Director for the Green Industrial Power Division at Infineon Technologies.

When matched with Infineon’s CoolMOS S7 switch, the isolator drivers enable switching designs with a much lower resistance compared to optically driven solid-state solutions. This translates to longer lifespans and lower cost of ownership in system designs. As with all solid-state isolators, the devices also offer superior performance compared to electromagnetic relays, including 40 percent lower turn-on power and increased reliability due to elimination of moving parts.

The family of devices is designed to be compatible with Infineon’s broad switching portfolio including Infineon’s CoolMOS S7, OptiMOS ^TM and linear FET portfolios.
