HEATSINK RECMMENDATIONS
We recommend that solid state relay modules be mounted to a heatsink sufficient to maintain the module’s base temperature at less than 850C 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.
The module should be mounted to the heatsink using two M3 screws.
