3EZ27D5-TP Datasheet/PDFDiodes - Zener - Single
The 3EZ27D5-TP is a type of Zener Diode and is a single component from the Zener Diode family. Zener Diodes are used primarily for voltage regulation and have both a cathode and an anode. The 3EZ27D5-TP has a breakdown voltage of 27 V, and is widely used for stabilizing small signals in cost-sensitive circuits.
Application Field
The 3EZ27D5-TP is used in a range of application fields such as consumer electronics, industrial electronics,and control systems. The device is also widely used in various power supply circuits like AC-DC, DC-DC, and DC-AC converters, voltage regulators and DC battery charger applications. It is also used in signal processing and data transmission networks, as well as in signal conditioning and control systems.
Working Principle
When a voltage is applied to the diode, electrons are injected into the depletion layer, creating a reverse electric current. The current removes the positive charge, resulting in a buildup of negative charge in the depletion layer, which eventually causes the electric field to become greater than the Zener voltage. The Zener voltage is the pressure required to breakdown the diode and reverse the flow of current. This is the basis of the Zener Diode\'s functionality.
Once breakdown has occurred, a small continuous current flows and the voltage at the diode terminals remains constant, irrespective of any increase in the applied voltage, as long as the current remains below the maximum ratings of the diode. This voltage regulation and constant voltage operation of the diode is crucial for maintaining the output of power supplies, which provide the necessary power for today\'s integrated circuits.
The 3EZ27D5-TP from the Zener Diode family is a commonly used device for low cost voltage regulation circuits. This diode can be used as both a current regulator and voltage regulator and can work in both directions, making it ideal for a wide range of applications.
