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