ELECTRICAL CHARACTERISTICS (Thermal Derating Curves):

HOW TO USE THESE CURVES
Knowing maximum load current and maximum ambient temperature, use derating curves to determine the minimum required heat sink and maximum allowable base plate temperature. On left hand power dissipation curve, locate the point corresponding to maximum load current. Extend a line to the right from that point to the intersection of vertical line on right hand chart corresponding to maximum ambient temperature. From heat sink curve, read directly or extrapolate required heat sink size. Extend the line farther to the right and read on the right hand scale the maximum allowable base plate temperature.

HEATSINK DIMENSIONS:

· We recommend that solid State Relay Modules be mounted to a heatsink sufficient to maintain the module's base temperature at less than 85 degrees 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 Coming 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 #l0 screws. The mounting screws should be torqued to 10 inch-pounds by alternately tightening the screws one quarter turn at a time.
