Optimizing the Lifetime of Optocouplers

Würth Elektronik Watts Up Podcast

When designing a circuit, one of the main considerations you need to take is the expected lifetime; not only based on the product itself, but also all the individual components included. For optocouplers, the performance degrades over time depending on the operating conditions. In this podcast, we'll give an introduction into how Wurth Elektronik tests the lifetime of its optocouplers and how you can calculate the expected lifetime of your application. We'll also give special tips and tricks into how to operate the optocouplers for increased lifetime. Click here to download the complete App Note, ANO006, or visit www.we-online.com/appnotes.
