The failure rate of SSRs ___ as the ambient temperature increases.

As the ambient temperature increases, the failure rate of solid-state relays (SSRs) increases primarily due to thermal stresses and the semiconductor materials used in their construction. High temperatures can lead to accelerated aging of the components, which impacts their reliability and may cause them to fail more frequently.

In environments where the temperature rises, SSRs can experience overheating, which exacerbates issues like junction temperature rise, affecting their electrical and thermal performance. Consequently, maintaining an optimal operating temperature range is crucial for the longevity and reliability of SSRs, as exceeding these limits can significantly raise the likelihood of failure.
