Schottky Rectifiers

  • B. Jayant Baliga


A Schottky rectifier is formed by making an electrically non-linear contact between a metal and the semiconductor drift region. The Schottky rectifier is an attractive unipolar device for power electronics applications due to its relatively low on-state voltage drop and its fast switching behavior. It has been widely used in power supply circuits with low operating voltages due to the availability of excellent devices based upon silicon technology. In the case of silicon, the maximum breakdown voltage of Schottky rectifiers has been limited by the increase in the resistance of the drift region. Commercially available devices are generally rated at breakdown voltages of less than 100 volts.
