Solid-State Relays

Vishay’s solid-state relays (SSRs) are designed for high reliability, high input-to-output isolation, and low on-resistance. With small dimensions, low power consumption, and bounce-free operation, they offer many advantages compared to mechanical relays. Vishay SSRs are perfectly suited to replace mechanical relays and are the ideal solution for signal switching in telecommunications, industrial automation, security systems, and metering applications.
