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 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. |
