Heat Sinks

PCH Series

INTRODUCTION:

Solid State Relays (SSRs) generate heat while operating primarily from the semiconductor junction of the output switching device. This can be a triac, SCR or

Mosfet. When utilizing an SSR it is important that the heat generated be managed via the use of the proper heat sink or alternative cooling method. Proper

cooling will allow for maximum performance from the SSR. The use of the correct heat sink has a direct influence on the maximum load current that can be

switched and the maximum ambient temperature the SSR can operate in.

Proper installation of a heat sink is just as important for proper heat dissipation. This includes utilizing a thermal transfer pad or thermal conductive grease to

fill the gap between the relay and heat sink and utilizing the proper torque while tightening the screws attaching the SSR to the heat sink.



Recommended Screw Torque is 15 to20 in lbs or 1.7 to 2.2 Nm.

For very high performance applications, air cooling may be required in addition to the heat sink. Failure to manage the dissipation of heat by the SSR during

usage may lead to failure of the SSR in either a short or open output.
