The FGH40T65SPD-F155 is an IGBT Transistor package with 40A peak current rating and 650V voltage rating, manufactured by ON Semiconductor. The package is a TO-247 style with three pins, for emitter, collector, and gate. It is designed for use in motor control, lighting, and power switching applications. It features an N-channel IGBT with an integral freewheeling diode, constructed using advanced processing techniques. It also has a temperature-dependent thermal shutdown capability to protect against over temperature operation.
