adum260n/adum261n/adum262n/adum263n data sheet rev. 0 | page 22 of 23 insulation wear out the lifetime of insulation caused by wear out is determined by its thickness, material properties, and the voltage stress applied. it is important to verify that the product lifetime is adequate at the application working voltage. the working voltage supported by an isolator for wear out may not be the same as the working voltage supported for tracking. the working voltage applicable to tracking is specified in most standards. testing and modeling have shown that the primary driver of long- term degradation is displacement current in the polyimide insulation causing incremental damage. the stress on the insulation can be broken down into broad categories, such as: dc stress, which causes very little wear out because there is no displacement current, and an ac component time varying voltage stress, which causes wear out. the ratings in certification documents are usually based on 60 hz sinusoidal stress because this reflects isolation from line voltages. however, many practical applications have combinations of 60 hz ac and dc across the barrier as shown in equation 1. because only the ac portion of the stress causes wear out, equation 1 can be rearranged to solve for the ac rms voltage, as is shown in equation 2. for insulation wear out with the polyimide materials used in these products, the ac rms voltage determines the product lifetime. 22 dc rmsac rms vvv ? ?
