Overview

This technical manual provides specifications and design details for the Infineon GS-EVB-IMS3 evaluation platform, developed to evaluate bottom-side cooled GaNPX E-mode transistors in high-power environments. The platform includes two specific daughter power board configurations: the 3kW GS-EVB-IMS3-66508B-GS and the 6kW GS-EVB-IMS3-66516B-GS. The document details the horizontal Insulated Metal Substrate (IMS3) design which achieves high thermal conductivity of 7.0 W/mK. It provides comprehensive technical data including thermal resistance comparisons, compatible driver motherboard options, double pulse test results, boost configuration performance, and full schematics with a bill of materials.
