  • 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 mounti ng surfaces and spread to a uniform depth of .002” to eliminate all air pockets.
  • The module should be mounted to the heatsink using two#10 screws. 10A Units 25A Units
