In summary, MOSFET relays are fully functional alternatives to electromechanical relays. MOSFET relays offer many advantages over their electromechanical counterparts. They have no physical contacts, a higher switching voltage, dielectric strength and a greater resistance to shock and vibration applications. Additionally, the audible click is not present in MOSFET relays due to the solid state nature of the device. Finally, OMRON offers their MOSFET relays in a VSON package, which adds a more compact size with similar electrical specifications when compared to the SSOP and USOP packages.
