Schottky diodes are semiconductor diodes which have a low forward voltage drop and a fast switching action. Although these are normally called Schottky diodes, they are also referred to as Schottky Barrier diodes, surface barrier diodes, hot carriers or hot electron diodes. Schottky diodes are often used for radio frequency (RF) applications as a mixer or detector diode. Schottky diodes are also used in power applications as rectifiers as well as a fundamental part of other devices.

You can purchase either wholesale or retail diodes from Schottky diode distributors. The Internet is a great place to locate distributors of Schottky diodes. When you shop for Schottky diode sellers for your business, here are some things that you should consider:

1. Determine what type of Schottky diodes that you need for the applications in your business.

2. Buy Schottky diodes from reputable manufacturers or distributors.

3. Understand the customer service policies of your Schottky diode suppliers.

Action Steps
The best contacts and resources to help you get it done

Get the Schottky diode that best suits your application

Consider the appropriate voltage of Schottky diode that you need for your business. Silicon-metal Schottky diodes have relatively low reverse voltage ratings. But recently-invested silicon carbide Schottky diodes are available in higher voltages and an even higher variant is available.

I recommend: TTI has a search page where you can search for Schottky diodes by voltage and stocks many of the lower voltage silicon-metal diodes. Mouser Electronics stocks silicon carbide Schottky diodes of higher voltage and allows you to select specifications for the Schottky diode.

Buy from Schottky diode distributors or Schottky diode manufacturers

You can purchase Schottky diodes from Schottky diode manufacturers or from Schottky diode distributors. If you purchase directly from the manufacturer, you may pay less than if you purchase from distributors of Schottky diodes. However, a Schottky diode distributor may have several different brands of Schottky barrier diodes available to offer your business a wider selection.

I recommend: Central Semiconductor and Skyworks Solutions are Schottky diode manufacturers. Digi-Key.com is a distributor website which has real-time stock status and pricing.

Understand the customer service policies of Schottky diode suppliers

You need to understand what type of support or technical service the suppliers of Schottky diodes will offer once you purchase the diodes for your business. Since businesses use Schottky diodes in electronic applications, it is important to know if the Schottky diode supplier is willing to answer questions after your purchase if you have any problems. You should also consider the location of the Schottky diode seller just in case you need personal follow-up.

I recommend: Diodes Incorporated gives you the option to ask technical questions once you have purchased a Schottky diode. ON Semiconductor has a wide selection of Schottky diodes and a listing of local sales and distributor offices.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Make sure to obtain customer service and return policies in writing.
• •  Ask for references of the Schottky diode seller so you can ask about other customers' experiences with the company.
