IXYS 4500V High Voltage Power MOSFETs are the highest voltage Power MOSFET product line in the industry in international standard size packages. The current ratings range from 200mA to 2A. They are specifically designed to address demanding, fast-switching power conversion applications requiring very high blocking voltages up to 4.5kV. Thanks to the positive temperature coefficient of their on-state resistance, these very high voltage MOSFETs are ideally suited for parallel device operation, which provides cost-effective solutions compared to series-connected, lower-voltage MOSFET ones. These can provide an optimal solution for applications such as capacitor discharge circuits, high-voltage automated test equipment, laser and x-ray generation systems, high-voltage power supplies, and pulse circuits.
