Solid State Relays (SSR)

Solid State Relays (SSRs) are electronic switching devices that use semiconductor components instead of mechanical contacts to control electrical loads. With no moving mechanical contacts, SSRs are suitable for applications requiring fast switching, frequent operation, low acoustic noise and long switching life. Omron describes SSRs as non-contact relays based on semiconductor switching technology for high-speed and high-frequency operation.

IC-VIETNAM supplies AC Solid State Relays, DC Solid State Relays, AC/DC SSRs, Zero-Cross SSRs, Random Turn-On SSRs, PCB Mount SSRs, DIN Rail SSRs, Chassis Mount SSRs and PhotoMOS / Photo Relays for heater control, industrial automation, motor control, lighting systems, temperature controllers, semiconductor equipment, instrumentation and power-switching applications.

Find Solid State Relays by output type, input voltage, load voltage, load current, circuit / contact form, zero-cross function, on-state resistance, isolation voltage, switching speed, mounting type, termination style, package, operating temperature, qualification and manufacturer. Major distributor filters also commonly include relay type, circuit, output type, input voltage, load voltage, load current, on-state resistance, mounting type and operating temperature.

SSRs are available for AC, DC and AC/DC loads. AC models may use zero-cross switching, which turns the relay on when the AC load voltage approaches zero, while other designs use non-zero-cross or random switching for applications requiring immediate activation. MOSFET-based photo relays can provide AC/DC load control and are commonly specified by load voltage, load current and I/O isolation voltage.
