Industrial Controls High Current Scr Gate Turn Off Thyristor SW20CXC565

Overview of Fast Turn-Off Thyristor (GTO)

A Fast Turn-Off Thyristor, commonly referred to as a Gate Turn-Off Thyristor (GTO), is a type of semiconductor device that can be turned on and off by its gate signal. Unlike standard thyristors, which can only be turned on by a gate signal and turned off by reducing the current flowing through them below a certain threshold (holding current), GTOs can be actively turned off by applying a negative gate pulse. This capability allows for more precise control over the device’s switching behavior.
GTOs are used in high-power applications such as motor drives, 電源, and inverters, where they facilitate rapid and controlled switching of large currents. They operate at higher currents and voltages than most other types of transistors, making them suitable for heavy-duty industrial and commercial applications.
