The various elements are as follows.

Variable diode. Discrete semiconductor products ship same day. They are most often used in devices that require electronic tuning such as radios. Thus this variable zener diode circuit is a better way for us.

But we can improve on this design by replacing the fixed voltage regulator with a variable voltage regulator such as the lm317t. Varactor diode or varicap diode a varactor diode is one sort of semiconductor microwave solid state device and it is used in where the variable capacitance is chosen which can be accomplished by controlling voltage. The varactor diode is manufactured in such as way that it shows better transition capacitance property than the ordinary diodes.

This is the series resistance within the diode and it varies according to. Then we can use 3 terminal voltage regulators and a suitable zener diode to produce a variety of fixed output voltages from our previous bench power supply ranging from 5v up to 12v. Varactor diode is also sometimes referred to as varicap diode tuning diode variable reactance diode or variable capacitance diode.

Varactor diode basics 3. Discrete semiconductor products diodes variable capacitance varicaps varactors are in stock at digikey. These diodes are also called as variceal diodes.

Varactor diodes also called varicaps are semiconductor devices that behave like variable capacitors. This circuit element represent the parasitic capacitance mainly arising. In electronics a varicap diode varactor diode variable capacitance diode variable reactance diode or tuning diode is a type of diode designed to exploit the voltage dependent capacitance of a reverse biased pn junction.

This element of the varactor diode represents the actual variable junction capacitance. Find out more in this article. In this video i have explained following topics regarding varactor diode.

Varactor diode characteristics. Varactor diode symbol 2. When reverse biased they have a capacitance that varies with an applied voltage.

Varactor diode internal structure 4. And zener diode features more than normal are higher input impedance 20 to 50 ohms rate under the maximum load. Variable capacitance diode is a type of semiconductor diode with special internal construction.
