What is a Fast Rectifier?

Rectification is the most popular use for diodes. Fast rectifiers convert alternating current (AC) to direct current (DC). They only allow one-way flow of electrons. Rectifiers have many uses and are often found serving as components of high-voltage direct current power transmission systems and DC power supplies. Fast rectifier diodes feature very low reverse recovery time, very low switching losses and low noise turn-off switching.

Types of Fast Rectifiers

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

The most common sizes for forward voltage are 1.1 V, 1.2 V and 1.3 V. We also carry fast rectifiers with forward voltage up to 8 V. Maximum reverse voltage can be up to 5000 V, with the most common sizes being 200 V, 400 V, 600 V and 1000 V.

Fast Rectifiers from Future Electronics

Future Electronics has a complete selection of fast rectifiers from several manufacturers that can be used as a fast recovery rectifier diode or a power rectifier diode. Simply choose from the fast rectifier technical attributes below and your search results will quickly be narrowed in order to match your specific fast rectifier application needs.

If you have a preferred brand, we deal with several manufacturers such as Diodes Inc., Fairchild, Micro Commercial Comp, ON Semiconductor and Vishay, among others. You can easily refine your fast rectifier product search results by clicking your preferred fast rectifier brand below from our list of manufacturers.

Applications for Fast Rectifiers:

Fast rectifier diodes are found in strobe applications that require high surge resistance as well as in the industrial, commercial and automotive sectors. High voltage resistance fast rectifier diodes, which are ideal for use in switching power supplies of all types, feature fast switching speeds along with improved efficiency and reduced loss. Fast rectifiers are also used in PDPs (sustain circuits) and PFC circuits. Also, detectors of radio signals serve as rectifiers.

Choosing the Right Fast Rectifier:

When you are looking for the right fast rectifiers, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Maximum Reverse Recovery Time (4 ns, 150 ns, 200 ns, 500 ns,…), Maximum Reverse Current (up to 280 A) and Forward Voltage (from 370 mV to 8 V) to name a few. You will be able to find the right power rectifier diode or fast recovery rectifier diode for any of your circuits.

Fast Rectifiers in Production Ready Packaging or R&D Quantities

If the quantity of fast rectifiers required is less than a full reel, we offer to customers many of our fast rectifier products in tube, tray or individual quantities that will help you avoid unneeded surplus.

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