Solid State Relays and Isolators - Infineon Technologies

Our solid-state relay range consists of HEXFET® power MOSFET and IGBT output photovoltaic relays plus Photovoltaic and Solid State Isolators that give designers the flexibility to create their own Solid State Relays. Option for Overcurrent, Switch Temperature and Miller Clamp protection are available in the Infineon Solid State Isolators family of products.

The solid state relays (SSRs) are on/off remotely controlled switches with complete galvanic isolation from input to output. No power supply is needed on the output. Using a relay allows for low-power control (e.g. from a microprocessor) over a high-power signal (e.g. switching of AC and DC loads) while providing galvanic isolation between the logic part of the circuitry and high power signals.  This isolation provides users with protection from electrical shocks and protects  electronics (e.g. microprocessors) from damage from high-voltage spikes.
