Solid State Relay Heatsink-FAQ's
What thermal loads require SSR heat sinks?
SSRs typically generate about 1-1.5 W per ampere on AC loads; heat sinks are necessary for currents above approximately 5 A to maintain safe junction temperatures.
What materials are used for SSR heat sinks?
High thermal conductivity aluminum alloys are standard-offering an optimal balance of performance, cost, and weight.
Which heat sink styles are available?
Commonly available in DIN-rail, panel, or chassis-mount types with extruded fin designs.
What thermal performance can be expected?
Thermal resistance ranges from approximately 0.5 to 3.0 °C/W depending on the SSR’s power rating and cooling requirements.
Can you produce custom designs?
Yes-fin dimensions, base size, surface treatments, and mounting features are fully customizable.
Are there options for space-limited setups?
Yes-bonded fin or high-density fin alternatives are available for compact applications requiring enhanced cooling in reduced footprints.
Do heat sinks improve SSR lifespan?
Absolutely-they lower operating temperatures, significantly improving SSR reliability and longevity.

Sinoextrud: Your Solid State Relay Heatsink Manufacturer
Solid state relays convert a significant portion of electrical load current into heat-without proper thermal management, component failure or reduced SSR lifespan may occur. Our heat sinks help dissipate this heat efficiently, preserving optimal SSR performance.
Manufactured from high-conductivity aluminum using extrusion for cost-effective thermal performance, these heat sinks are designed for versatile mounting formats such as DIN-rail or panel installations.
Thermal resistance is engineered based on SSR current load-ranging from approximately 0.5 to 3 °C/W-to ensure the junction stays within safe limits for your specific application.
We customize solutions to your design needs-including fin structure, form factor, surface finish, and mechanical features-allowing seamless integration with your SSR modules.
Whether for prototyping or mass manufacturing, our SSR heat sink solutions deliver durability, repeatable quality, and enhanced operational reliability for global industrial systems.
