## **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.
