What Is a Fast Thyristor KK?
A Fast Thyristor KK is a high-speed semiconductor switching device designed to handle high voltage and current with rapid turn-on and turn-off capabilities. Unlike conventional thyristors, it features reduced switching time, making it ideal for high-frequency applications.
Basic Structure
The Fast Thyristor KK typically consists of four semiconductor layers arranged in a PNPN configuration. These layers form three junctions that allow controlled current flow. Its main terminals include:
