Electrical devices that have switching functionality (relays, circuit breakers, fuses, etc) usually have an electromechanical part that physically switches "on and off" between a set of contacts. This part is prone to wearing out, creating faults or over-heating.

Using Infineon components you can replace the mechanical, or moving part with MOSFET (Fet) based technology that provides improved reliability, increases life-time use all in a package with advanced control and protection methods.

When these traditional, electromechanical products are upgraded inside with Infineon technology they become Super Solid-State Solutions (S4) suitable for static switching applications.

The benefits of transitioning to a solid-state solution is dependent on the particular product itself, but if we took an example, such as relays, the benefits of a solid-state relay vs an electromechanical relay can be found here:

Advantages of a solid-state relay:

• no mechanical contact and moving parts,
• longer electrical and mechanical life expectancy and higher reliability,
• higher shock and vibration resistance,
• it does not bounce or generate an electrical arc,
• typically far lower power consumption than EMRs.
