 MOS Relay

MOS Relay are classified to semiconductor relays that have no moving contact, therefore they are superior to conventional electro-mechanical relays in life-expectance and reliability of contacts, operation speed, and their sizes.


But they also distinguish themselves from other switching solutions that utilize photo-couplers, photo-transistors etc. MOS Relay have MOSFET for output, therefore they are the most suitable devices for small analog signal switching.


MOS relays find applications in various electronic systems due to the characteristics, such as fast switching speed, low power consumption, high reliability and compact size.
