Lock-in thermography for the localization of prebreakdown leakage current on power diodes

Abstract

In this paper we show how the Lock-In Thermography (LIT) technique is a valid choice to obtain information on the pre-breakdown leakage current distribution on power diodes. To do this we describe the LIT principle and our in house made experimental set-up. We finally show interesting experimental results on power Schottky diodes.
