Commutation Behavior of Diffused High-Current Rectifier Diodes

This paper suggests a practical manner in which the commutation characteristics of a rectifier diode may be presented. It gives quantitative recovery data for two popular types of diffused 250-ampere rectifier diodes in terms of circuit parameters. The recovered charge of the diode under prevailing circuit conditions is used, and quantitative data are given for the selection of appropriate protective circuitry.
