What is the life data on a SSR?

Causes and Fixes

Unlike a typical electromechanical relay, there are several variables that will directly impact the life expectancy of a solid-state relay in a given application.
These variables primarily revolve around the electrical characteristics of the application, such as load current, the duty-cycle of the load, the ambient temperature inside the panel, surge currents, etc. However, mechanical issues such as the mounting method, available airflow, and thermal interface between the relay and the panel / heat sink also impact the relays life expectancy.
Therefore, we provide an estimated MTBF specification range based on historical observation.
The MTBF rating for our solid-state relays is >2 million hours with a quality level of approximately 10PPM.
