摘要：肖特基二極管具有開關頻率高和正向壓降低等優點，在低壓、大電流輸出場合常被用作高頻整流，在高頻下用于檢波和混頻，在高速邏輯電路中用作箝位，在IC中也常使用SBD，如SBD-TTL集成電路早已成為TTL電路的主流，在高速計算機中被廣泛采用。SBD是利用金屬與半導體接觸形成的金屬-半導體勢壘制成的，因此，它是一種熱電子發射二極管，隨著制造工藝的不斷完善及特殊材料的出現，肖特基勢壘柵FET及其高速大規模集成電路(LSI)和超大規模集成電路(VLSI)領域的廣泛應用，肖特基二極管的應用范圍也越來越廣。

Abstract: Schottky diodes with a high switching frequency and positive pressure to reduce the advantages of the low-pressure, high current output high-frequency occasions are often used as high-frequency, high frequency used for detection and mixing, in the high-speed logic circuits used to clamp，The IC also frequently used in the SBD, such as the SBD-TTL IC TTL circuit has become the mainstream in high-speed computers are widely used in. SBD is the use of metal and semiconductor contact with the formation of metal - semiconductor barrier made of, so it is a thermal emission diode, with the manufacturing process of continuous improvement and the emergence of special materials, Schottky barrier gate and high-speed FET Large-scale integrated circuit (LSI) and ultra-large-scale integrated circuits (VLSI) wide field of applications, Schottky diodes on the application of more and more widely.
