The GWA80H65DFB, also known by the ST part number STGWA80H65DFB, is a Trench Field‑Stop IGBT engineered for high-speed switching applications. Featuring an integrated ultra-fast soft recovery diode, this device offers superior efficiency in hard-switching environments such as solar inverters, high-frequency converters, motor drives, and UPS systems. The tight parameter distribution and positive saturation voltage temperature coefficient make it optimal for demanding, parallel-operated systems. Its TO‑247 long-lead package provides robust thermal handling and easy heatsink integration
