Extensive Catalog of Rectifier Diodes at MICROS

In this category, MICROS offers a wide range of semiconductor rectifier diodes. We provide high-quality, specialized solutions for specific applications, including fast and ultrafast rectifier diodes for power electronics projects, diodes for AC voltage rectification, and switching elements for rapidly changing digital and analog signals, available in both through-hole and surface-mount packages.

What is a Rectifier Diode?

A rectifier diode is a semiconductor device used for rectifying alternating current (AC) and other electrical signals. A rectifier is an electronic solution that converts alternating current (AC), which periodically reverses direction, into direct current (DC), which flows in only one direction. This process is essentially rectifying the direction of current flow.

A rectifier diode is essentially a cased PN junction, which is a passive component (an electronic solution that does not generate electrical energy). Rectifier diodes have an asymmetric construction, conducting current differently in each direction. Thus, they are capable of "rectifying" the bidirectional AC current from the power grid and efficiently converting it into unidirectional DC current.

Rectifier Diode Symbol

In electronic schematics, the rectifier diode symbol appears as an arrow with a line at its end (the base of the arrow represents the anode (A), and the tip (line) represents the cathode (K)). The orientation of the arrow indicates the conventional direction of current flow through the diode when it is forward-biased. In industry literature, other abbreviations such as rectifier diode notation A for "Anode" and C for "Cathode" are also used.

The "p" region is connected to the anode, while the "n" region is connected to the cathode. Conduction of the diode occurs when a positive voltage is applied to the anode.

Functions and Applications of Rectifier Diodes

Rectifier diodes are most commonly used in DC power supply circuits, serving as a fundamental element in many electronic devices and installations. They are used as parts of DC power supplies and high-voltage DC transmission systems.

Rectifier diodes can also be used for detecting radio signals or the presence of a flame, such as in gas heating systems.

Our rectifier diodes excel in:

• Power supply circuits and converters that transform AC from the power grid into DC for powering electronic devices,
• Inverters, voltage and frequency converters,
• Stabilizing and surge protection systems,
• Systems protecting devices against incorrect power connections (reverse polarity).
