Diodes - Zener - Single

Zener diodes are semiconductor devices used to regulate voltage. The 1N5920E3/TR13 is an example of a single Zener diode, capable of handling up to 1 watt of power. It serves a number of application fields, each of which depends upon the Zener diode\'s ability to regulate voltage. The diode\'s working principle reveals how its properties enable this effect.

Application Fields

1N5920E3/TR13 Zener diodes can be found in a number of application fields. It can be used to create a voltage reference from either AC or DC sources, as in charging circuit systems or digital-to-analog converters. The diode also supplies voltage stabilization in phase-locked loop circuits, as well as fed back to circuit transistors. Additionally, the diode can be used to provide voltage regulation in protection circuits and switches.

Working Principle

To understand how it works, it is first important to note that a Zener diode\'s reverse break down is fixed. This means that the diode allows current to flow when the reverse bias voltage that is applied to it reaches a certain fixed point, known as its breakdown voltage. A certain amount of current will then flow out of the Zener diode until the voltage reaches its Zener voltage.

Although there is still a current flow, its magnitude is limited, as the voltage has become stabilized. This stabilization of voltage is the voltage regulation effect of the Zener diode. To summarize, a 1N5920E3/TR13 Zener diode is able to regulate voltage due to its reverse breakdown voltage, which allows a fixed current to flow when the voltage reaches the diode\'s breakdown point.

The Zener diode\'s 1 watt rating, along with its features, make it an ideal semiconductor for a variety of applications, including voltage references and voltage stabilization. Its fixed breakdown voltage is the working principle behind its effectiveness.
