Solid State Relay Heatsink
Heatsinks are required to ensure the proper operation and reliability of solid state relays.
Heat and thermal fatigue created by the changing temperature within a solid state relay reduce the life expectancy and reliability of the product. Lower operating temperatures and/or thermal excursions within the relay improves overall reliability. Conversely, higher operating temperatures and/or thermal excursions within the relay reduce overall reliability. Therefore, utilizing the proper heat sink improves the overall reliability of a solid state relay by reducing internal temperature and the thermal excursions.
Heatsinks are made of thermally conductive material(s) and are intended to reduce the temperature of a heat generating element mounted to it's surface. Generally, heat sinks are made from high thermal conductivity materials such as aluminum or copper. They are available in a variety of standard extrusion profiles or may be custom extruded per the customer's specific requirements.
