What is Zener diode and its properties?
Zener diodes are heavily doped than ordinary diodes. They have extra thin depletion region. When we apply a voltage more than the Zener breakdown voltage (can range from 1.2 volts to 200 volts), the depletion region vanishes, and large current starts to flow through the junction.
How do you calculate Zener current?
The maximum current is calculated by dividing the power rating by the Zener voltage: I=P/V = 3W/12V = 0.25A.
What are applications of diode?
The application areas of diodes include communication systems as limiters, clippers, gates; computer systems as logic gates, clampers; power supply systems as rectifiers and inverters; television systems as phase detectors, limiters, clampers; radar circuits as gain control circuits, parameter amplifiers, etc.
Is important application of Zener diode?
The major application of a Zener diode in the electronic circuit is as a Voltage Regulator. It provides a constant voltage to the load from a source whose voltage may vary over a sufficient range.
Why Zener diode is used in Rectifier?
A complete and stabilized power supply can be obtained by using the rectifier diodes to change the AC power to DC power. The rectified voltage is filtered to reduce the ripple on the rectified waveform. A Zener diode is then used to regulate the voltage to its desired final value.
What is V-I characteristics of Zener diode?
V-I Characteristics of Zener Diode. Zener Diode is a reverse-biased heavily-doped PN junction diode which operates in the breakdown region. The reverse breakdown of a PN- junction may occur either due to Zener effect or avalanche effect.
What is Zener voltage?
The Zener voltage is the voltage at which the depletion region completely vanish. The reverse bias applies across the diode increases the intensity of electric field across the depletion region. Thus, it allows the electrons to move from the valence band of P-type material to the conduction band of N-type material.
What does Zener mean?
Jump to navigation Jump to search. Zener can refer to: Zener diode, a type of electronic diode. Zener effect, a type of electrical breakdown which is employed in a Zener diode. Zener pinning, the influence of a dispersion of fine particles on the movement of low- and high angle grain boundaries through a polycrystalline material.
What is a voltage reference diode?
A voltage reference diode is a device that is able to maintain an accurate voltage level given a suitably wide range of reverse current through it. With this characteristic, a voltage reference diode is very useful in providing precision voltage levels, such as in regulated power supplies…
