Heatsink Recommendations
We recommend that solid state relay modules be mounted to a heatsink sufficient to maintain the modules base temperature at less than 85C
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.
