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

all air pockets.

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