Traditional electromagnetic relays, (EMRs), are still popular choices for certain applications, particularly where high-power switching is required. However, the characteristics of solid-state relays (SSRs), particularly MOSFET types, mean they are being employed in a growing range of applications.

In this week's post on Engineers' Insight, we look at how MOSFET relays work, and how their characteristics can help address specific design challenges in modern applications.
