The main working principle of IGBT is to control the flow of holes and electrons in the semiconductor layer by controlling the gate voltage, so as to control the on-off and off-off of the device. The Chao microfocus Trench-FS IGBT structure provides customers with a good compromise choice between on-state loss and switching loss, on-state loss and device voltage withstand. The series products are widely used in consumer, industrial control and other fields.
