Since the mid-nineteen seventies the “enhancement-mode” MOSFET has been the subject of almost continuous global research, development, and refinement by both the semiconductor industry and academia.
Applications like constant current sources, solid-state relays, telecom switches and high voltage DC lines in power systems require N-channel Depletion mode power MOSFET that operates as a normally ...
The power semiconductor evolution started with germanium and selenium devices that succumbed to silicon types around the 1950s. Broader silicon usage stemmed from its improved physical properties ...
