As more processing power and more complex loads are placed on-orbit or into deep space missions, it is sometime necessary to parallel two or more power switches. However, conventional power device packages, such as the FSMD-A/B/C/D and their I/O pad provisioning make it difficult to accomplish paralleling these devices in a performance-conscious manner. When paralleled, the gate and source-sense pads on these packages either serve to block the most efficient/shortest interconnect from package-to-package for the drain and source connections or for the gate and source-sense pads. So in parallel configurations, there is always a compromise between optimized drain-source load-circuit performance and gate-source-sense drive-loop performance. This article introduces the FSMD-G discrete HEMT package and explains how the reconfiguration of its I/O pads overcomes these limitations when paralleling GaN HEMTs.
