What is a Standard Rectifier?
A rectifier diode lets electrical current flow in only one direction and is mainly used for power supply operation. Rectifier diodes can handle higher current flow than regular diodes and are generally used in order to change alternating current into direct current. They are designed as discrete components or as integrated circuits and are usually fabricated from silicon and characterized by a fairly large P-N-junction surface. This results in high capacitance under reverse-bias conditions. In high-voltage supplies, two rectifier diodes or more may be connected in series in order to increase the peak-inverse-voltage (PIV) rating of the combination.

Types of Standard Rectifiers:
There are many different kinds of standard rectifiers, the most common types categorized by maximum reverse current, maximum peak current, maximum reverse voltage, forward voltage, packaging type and maximum average rectified 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 1 A, 1.5 A, 3 A, 5 A and 6 A. We also carry standard rectifiers with maximum average rectified current as high as 400 A. Forward voltage can range from 1.1 mV to 1.3 kV, with the most common standard rectifier semiconductor chips having a forward voltage of 1.1 V or 1.15 V.

Applications for Standard Rectifiers:
Standard rectifiers can be found regulating the power in computers and the electrical power in motor vehicles. They can also be used in battery chargers for rechargeable batteries, computer power supplies and vehicle batteries. Also, while rectifier diodes are often used for AC to DC conversion, diodes with rectifying characteristics are found in other uses than in electronics. For example, a diode is used in the detector of radios in order to perform radio demodulation.

Cross Reference:

Gas-filled surge arresters are classical components for protecting the installations of the telecommunications. It is essential that IT and telecommunications systems -with their high-grade but sensitive electronic circuits – be protected by arresters. They are thus fitted at the input of the power supply system together with varistors and at the connection points to telecommunication lines. They have become equally indispensable for protecting base stations in mobile telephone systems as well as extensive cable television (CATV) networks with their repeaters and distribution systems.

These protective components are also indispensable in other sectors:

• In AC power transmission systems, they are often used with current-limiting varistors
• In customer premises equipment such as DSL modems,WLAN routers, TV sets and cable modems
• In air-conditioning equipment

The integral black-box concept offers graduated protection by combining arresters with varistors, PTC thermistors, diodes and inductors to create an ideal solution for many applications.

Crystal oscillators are used in a variety of applications. In some instances crystal oscillators may be used to provide a cheap clock signal for use in a digital or logic circuit. In other instances they may used to provide an RF signal source. In view of the fact that quartz crystals offer a very high level of Q and they are stable, crystal oscillators are often used in oscillator circuits to provide stable, accurate radio frequency signals.

There is a great number of different types of circuit that can be used for crystal oscillators, each one having its own advantages and disadvantages. One of the most common circuits used for crystal oscillators is the Colpitts configuration as shown below.

In this configuration, the crystal operates in a parallel mode. When running in this mode, the crystal should be presented with a load capacitance to operate on its correct frequency. This load capacitance is specified with the crystal and is typically 20 or 30 pF. The crystal oscillator circuit will be designed to present this capacitance to the crystal. Most of this will be made up by the two capacitors C1 and C2, although the remaining elements of the circuit will provide some capacitance.
