FAE Expert Insights
"The RGTH80TK65D extends the RGTH series to 80A for higher power applications. This device is perfect for 40-50kW motor drives and commercial solar inverters. The saturation voltage is excellent at 1.65V, even lower than the 60A version due to larger die size. The integrated diode handles the full 80A with fast recovery. For high-power industrial applications where SiC is still too expensive, this IGBT delivers excellent value. I've used it in large VFD and solar projects with great success."
