Especially when electromechanical relays' lifetime is too short to fulfill the application's requirements, the advantages these new PhotoMOS relays, available from Ramelec Electronics  offer, come into play.

By employing modern MOSFET transistors for the output of the AQV251G relays, it is possible to realize a typical ON-resistance of just 0,035Ω. Because there is negligible loss at the output, the maximum continuous load current at room temperature can be specified with a current of 3.5A.

The most important features of the PhotoMOS relays are:

  • Unlimited lifetime
  • Output rating 30V / 3.5A
  • Electrical characteristics are constant
  • Low control current
  • Fast, contact-free and silent switching
  • Insulation between input and output circuits
  • I/O insulation 1.5kVrms
  • Compact 6-pin DIP / SMD package

High power PhotoMOS relays are ideally suited for all application areas that require an extremely long lifetime and constant electrical characteristics. These PhotoMOS relays are used to realize maintenance-free PLC outputs, industrial facilities and, due to their low ON-resistance, in measurement technology..
