What is a Schottky Diode?

A Schottky diode, also known as a hot carrier diode, is a semiconductor diode which has a low forward voltage drop and a very fast switching action. There is a small voltage drop across the diode terminals when current flows through a diode. A normal diode will have a voltage drop between 0.6 to 1.7 volts, while a Schottky diode voltage drop is usually between 0.15 and 0.45 volts. This lower voltage drop provides better system efficiency and higher switching speed. In a Schottky diode, a semiconductor–metal junction is formed between a semiconductor and a metal, thus creating a Schottky barrier. The N-type semiconductor acts as the cathode and the metal side acts as the anode of the diode. This Schottky barrier results in both a low forward voltage drop and very fast switching.

Types of Schottky Diodes

There are many different kinds of Schottky diodes and at Future Electronics we stock many of the most common types categorized by maximum average rectified current, maximum reverse voltage, maximum reverse current, forward voltage, packaging type and maximum peak current. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for maximum average rectified current are 70 mA, 100 mA, 200 mA and 1 A. We also carry Schottky diodes with maximum average rectified current as high as 300 A. Forward voltage can range from 280 mV to 430 V, with the most common Schottky diode semiconductor chips having a forward voltage of 800 mV or 1 V.

Applications for Schottky Diodes:

Schottky diodes are useful in voltage clamping applications and prevention of transistor saturation due to the higher current density in the Schottky diode. Also, because of the low forward voltage drop in a Schottky diode, less energy is wasted as heat, therefore making them an efficient choice for applications that are sensitive to efficiency. Because of this, they are used in stand-alone photovoltaic systems in order to prevent batteries from discharging through the solar panels at night as well as in grid-connected systems containing multiple strings connected in parallel. Schottky diodes are also used as rectifiers in switched-mode power supplies.

Choosing the Right Schottky Diode:

When you are looking for the right Schottky diodes, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Maximum Average Rectified Current (70 uA, 70 mA, 100 mA, 200 mA,…), Maximum Peak Current (200 uA, 600 mA, 1A,…) and Forward Voltage (280 mV to 430 V) to name a few. You will be able to find the right semiconductor chip from several manufacturers that can be used for any other circuits requiring a Schottky barrier diode.

Schottky Diodes in Production Ready Packaging or R&D Quantities

If the quantity of Schottky diodes required is less than a full reel, we offer customers many of our programmable Schottky diode products in tube, tray or individual quantities that will avoid unneeded surplus.

In addition, Future Electronics offers clients a unique bonded inventory program that is designed to eliminate potential problems that may arise from an unpredictable supply of products containing raw metals and products with erratic or long lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
