The Schottky diode consists essentially of a metal-semiconductor interface. Because of its low forward voltage drop and high switching speed, the Schottky diode is widely used in a variety of applications, such as a boost diode in power conversion circuits. The electrical performance of a Schottky diode is, of course, subject to physical trade-offs, primarily between the forward voltage drop, the leakage current, and the reverse blocking voltage. The Trench Schottky diode is a development of the original Schottky diode, providing greater capabilities than its planar counterpart. In this whitepaper, the structure and the benefits of Trench Schottky rectifiers are discussed.
