STMicroelectronics SGT350R70GTK E-Mode PowerGaN Transistor

STMicroelectronics SGT350R70GTK E-Mode PowerGaN Transistor is a high-performance enhancement-mode PowerGaN transistor optimized for efficient power conversion in demanding applications. With a drain-source voltage rating of 700V and a maximum on-resistance of 350mΩ, the STMicroelectronics SGT350R70GTK delivers low conduction losses and fast switching capabilities thanks to Gallium Nitride (GaN) technology. Packaged in a thermally enhanced DPAK format, the device supports high current handling and improved heat dissipation, suitable for high-density power designs. A low gate charge and output capacitance enable high-frequency operation, ideal for use in power factor correction (PFC), resonant converters, and other advanced power topologies in industrial, telecom, and consumer electronics sectors.
