Diodes

Diodes are electronic devices with two terminals. They are most commonly used to allow an electric current to flow in one direction and block it from flowing in the other, but depending on the diode technology in effect, can be used to perform a variety of more complicated functions. General purpose diodes are most commonly made from semiconductor materials like silicon and germanium.

Electronic component diodes can be used in nearly every electronic application. Whether your business is in the military, automotive, aerospace, or communications industry, you can find electronic diode suppliers catering to your need. Find a variety of options, including:

Look through online catalogs at multiple electronic diode products.
Turn to an electronic diode supplier for high voltage diodes.
Save on wholesale and surplus diodes.

Browse online catalogs for the right electronic component diode products

Diode suppliers with online catalogs offer an easy way to view multiple products and compare product specifications and prices. If you're not certain what electronic diodes are right for your business, do some quick research with the help of online listings telling you all you need to know about diverse general purpose diode products.
Try: Arrow Electronics is a global provider of industrial products, including a wide variety of diodes. Browse through their product listing or use their advanced product search to look for the specific diode you require. C&H Technology has a large online catalog of standard and fast recovery diodes in multiple varieties.

Find high voltage diodes online

If you need diodes that can handle greater currents with high levels of precision, contact a diode supplier specializing in high voltage diodes.
Try: Voltage Multipliers provides high voltage diodes capable of handling up to 20 KV. Electronic Devices sells a wide variety of diodes and rectifiers of all voltage capacities.

Save when you purchase diodes from wholesale dealers

If you need large numbers of general purpose diodes or are just looking for a great deal on electronics, turn to wholesale suppliers of diodes. Wholesale and surplus suppliers can offer diodes at prices much lower than standard listings, especially when you buy in bulk.
Try: Q Components provides a wide variety of wholesale electronic products, including diodes. Find models from a number of diode manufacturers, view photos of multiple products, and request price quotes on all diodes directly from their website. Surplus Sales of Nebraska carries surplus and hard to find diode products. Get deals on orders of multiple hundreds or thousands of diodes.

If you can't find standard electric diodes that fit your needs, contact a diode manufacturer about engineering a custom diode for your company. Present your own design or work with engineers to create a product that meets all the specifications necessary for your industrial applications.

Tips & Advice to help you make your decision on Diodes

Diodes are electrical components that control the flow of current in an electrical system, such as on a circuit board in a computer. Electrical current can flow in the forward or reverse direction. The diode performs the same function as a check valve or a train track switching lever. It allows the flow of current to go in one direction, while preventing current flow in the other.

When diodes allow current to flow, they are called forward-biased. When they prevent the flow of current, they are called reverse-biased. Diodes are either semiconductors or vacuum tubes. Semiconductor diodes are by far the most common type and come in two capacities. Semiconductor signal diodes are used ... more
