Normal diodes will also break down with a reverse voltage but the . Zener diodes have a highly doped p-n junction. The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached. If we connect a diode and resistor in series with a DC voltage source so that the diode is forward-biase the voltage drop across the diode will remain fairly constant over a wide range of power supply voltages as in Figure below (a). According to the “ diode equation” here, the current through a forward-biased PN junction is .

A tutorial on zener diodes and how to use them as voltage clamps, voltage regulators, and how to create audio. A zener diode is a p-n junction semiconductor device that is designed to operate in the reverse breakdown region. It also permits to flow in the reverse direction. ON Semiconductor supplies zener diodes for voltage regulation circuits.

Zener Diodes are available at Mouser Electronics. To construct a zener diode voltage regulator and measure its line and load regulation. When biased in the forward direction it behaves just like a .

The Zener voltage of a standard diode is high, but if a reverse current above that value is allowed to pass through it, the diode is permanently damaged. When a reverse current above the Zener voltage passes through a Zener . Breakdown voltage is also known as Zener . These diodes are rated for 5. When the maximum voltage rating is exceede however, a large reverse current is produce and the diode becomes destroyed. This destruction occurs at what is known as the reverse breakdown voltage or peak inverse voltage (PIV). Устойчивое сочетание (термин).

Используется в качестве именной группы. They are available with power ranges from less than 3mW to over 5mW and include a number of automotive- qualified parts. Products include the 5mW PLZ series, which features a MicroMELF . Distribution Inventory.

In this lesson we define the zener diode and describe its characteristics. Also, we describe how the zener diode is used as a voltage regulator, a. Semtech offers, non cavity, category I, double plug construction, 1. They are most commonly used to provide an accurate reference voltage.

All diodes allow current to pass in one direction only. In normal use, diodes never suffer a reverse breakdown which would destroy the diode. This voltage regulator is a p-n junction diode that has a precisely tailored impurity distribution to provide a well-defined breakdown voltage. It can be designed to have a breakdown voltage over a wide range from 0.
