Depletion Mode MOSFET Devices
Our N-channel depletion mode field effect transistors (FET) utilize a proprietary third generation vertical DMOS process. The third generation process realizes world-class, high voltage MOSFET performance in an economical silicon gate process. The vertical DMOS process yields a robust device for high power applications with high input impedance. These highly reliable FET devices have been used extensively in IXYS Integrated Circuits Division's solid state relays for industrial and telecommunications applications. See AN-500, MOSFET Application Note.
