High-Voltage Diffused Step Recovery Diodes: II. Theory

Abstract

Approximate analytical formulas are derived to evaluate the main characteristics of diffused step recovery diodes, which operate as current interrupters in high-power nanosecond pulse generators with intermediate inductive energy storage: the spurious prepulse voltage, characterizing the resistive loss in diffused step recovery diodes; amplitude; front duration; maximum voltage rise rate, and duration of the pulse formed on an active load. Similar formulas for epitaxial step recovery diodes, partially obtained for the first time and partially refining previous results, are given for comparison.
