Diodes can switch analog signals. A reverse biased diode appears to be an open circuit. A forward biased diode is a low resistance conductor. The only problem is isolating the AC signal being switched from the DC control signal. The circuit in Figure below is a parallel resonant network: resonant tuning inductor paralleled by one (or more) of the switched resonator capacitors. This parallel LC resonant circuit could be a preselector filter for a radio receiver. It could be the frequency determining network of an oscillator (not shown). The digital control lines may be driven by a microprocessor interface.

Diode Package:

Functionally, Zener diodes are used as regulators, limiters and to control output switching. When used as regulators, the constant reverse voltage of Zener diodes allows for the regulation of output voltage against both variations in the input voltage from an unregulated power supply and from variations in the load resistance. The current traveling through Zener diodes changes to keep the voltage within the threshold of Zener action and the maximum power it can dissipate. Zener regulators tend to most efficiently function when constant voltage is applied, especially when used in conjunction with regulated power supplies, and for limiter applications.

Zener limiters are constructed with two opposing Zener diodes. Each individual diode can limit one side of a sinusoidal waveform to Zener voltage while keeping the other side near zero. When the two opposing Zener diodes are paired, the waveform is limited to Zener voltage on both polarities.

Zener diodes are also used to control output switching. In this application, Zener diodes switch the output between voltages. This is determined by the changes in input voltage through the diode. The output circuit amounts to a Zener regulator that switches from one Zener voltage to the other on transition through the Zener diode.

Kingtronics supply all kinds of Zener Diodes BZV55C & ZMM55C, http://www.kingtronics.com/pdf/BZV55C.pdf has detailed introduce Zener Diode’s features and types.

There are many different types of diodes that are available for use in electronics design. Different semiconductor diode types can be used to perform different functions as a result of the properties of these different diode types.

Semiconductor diodes can be used for many applications. The basic application is obviously to rectify waveforms. This can be used within power supplies or within radio detectors. Signal diodes can also be used for many other functions within circuits where the "one way" effect of a diode may be required.
 
Kingtronics sell many different types of diode, in our website we have a full products list of diode & rectifiers, please go to Products link and have a view.

Kingtronics produce and sell many different kinds of diodes, and at Kingtronics’ s blog we will tell you how to test a Diode:

You can use a multimeter or a simple tester (battery, resistor and LED) to check that a diode conducts in one direction but not the other. A lamp may be used to test a rectifier diode, but do NOT use a lamp to test a signal diode because the large current passed by the lamp will destroy the diode!

Using these way you can confirm if your Diode is working or not. Kingtronics diode include: M7, 1N4001S-1N4007S, 1N4001-1N4007, 1N5391-1N5399, RL201-RL207, 1N5400-1N5408, 6A05-6A10, FR101-FR107, 1N4933-1N4937, FR151-FR157, FR201-FR207, 1N5817-1N5819, 1N5820-1N5822, LL4148, BZV55C & ZMM55C, RS1M, SM4007 melf, UF4007.If you are interested in these diode, welcome to visit www.kingtronics.com.

Rectifiers find a use in detection of amplitude modulated radio signals. The signal may be amplified before detection, but if un-amplified, a very low voltage drop diode must be used. When using a rectifier for demodulation the capacitor and load resistance must be carefully matched. Too low a capacitance will result in the high frequency carrier passing to the output and too high will result in the capacitor just charging and staying charged.

Kingtronics’s fast recovery rectifier diodes are very popular in the overseas market, According to the rectifier’ s application , Our Kingtronics managing ordinary rectifier diodes, ultra-fast rectifier diodes. In our Kingtronics website www.kingtronics.com ,we have detailed PDF about all kinds of diodes & rectifiers.

Zener diodes are used to maintain a fixed voltage. They are designed to 'breakdown' in a reliable and non-destructive way so that they can be used in reverse to maintain a fixed voltage across their terminals.

Zener diodes can be distinguished from ordinary diodes by their code and breakdown voltage which are printed on them. Zener diode codes begin BZX... or BZY... Their breakdown voltage is printed with V in place of a decimal point, so 4V7 means 4.7V for example.

Kingtronics supplies BZV55C/ZMM55C-SERIES with Low zener impedance,Low regulation factor,Glass passivated junction,High temperature soldering guaranteed:260 C/10S at terminals. Please link http://www.kingtronics.com/pdf/BZV55C.pdf ,you will see all series of our Zener diodes.

The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction) while blocking current in the opposite direction (the reverse direction). Thus, the diode can be thought of as an electronic version of a check valve. This unidirectional behavior is called rectification, and is used to convert alternating current to direct current, and to extract modulation from radio signals in radio receivers.

Different types of diode will have different function, this is depends on their voltage, temperature, and other factor. So it is very important when you check your diode, Our Kingtronics provide diode's detailed function. If you have any problems, please look for some suggestions in www.kingtronics.com.

In electronics, a diode is a two-terminal electronic component that conducts electric current in only one direction. The term usually refers to a semiconductor diode, the most common type today. This is a crystalline piece of semiconductor material connected to two electrical terminals.A vacuum tube diode (now little used except in some high-power technologies) is a vacuum tube with two electrodes: a plate and a cathode.
