## **Electrical Characteristics (Thermal Derating Curves)** 

## **Operating Diagram** 

## **Heatsink Recommendations** 

- We recommend that solid state relay modules be mounted to a heatsink sufficient to maintain the module’s base temperature at less than 85°C under worst case ambient temperature and load conditions. 

- The heatsink mounting surface should be a smooth (30-40 micro-inch finish), flat (30-40 micro-inch flatness across mating area), un-painted surface which is clean and free of oxidation. 

- An even coating of thermal compound (Dow Corning DC340 or equivalent) should be applied to both the heatsink and module mounting surfaces and spread to a uniform depth of .002” to eliminate all air pockets. 

Random Turn-on units have a Random Turn-on circuit instead of zero voltage circuit 

- The module should be mounted to the heatsink using two #10 screws. 

## **Outline Dimensions** 

Input Terminal Connectors are available from several different manufacturers. 

TE P/N: 103976-3 or 640440-4 Methode P/N: 1300-004-422 

Consult your local distributor for these or equivalent connectors.
