Inside iCoupler® Technology:
Waveform Voltage Conventions for iCoupler Digital Isolators
Digital isolators are characterized by several voltage ratings that determine the capability to endure various stress levels and durations. Working voltage, withstand voltage, and surge voltage are all examples of these ratings. It's important to understand how these voltages are defined, with relation to the isolation barrier, to properly determine the suitability for a particular application.
