The Z4KE130-E3/73 is a single Zener diode. It is quite reliable, easy to use and identify, and offers a wide range of features. It is well suited for use in a variety of electrical applications.

Application Field

The Z4KE130-E3/73 is mainly used in circuits that require a fast switching action, such as relay and lamp drivers. It can also be used to control the protection of power supplies, to regulate voltage, and for rectification of alternating current (AC). It is often used in AC-DC transformers, clamping diodes, chemical and photochemical sensors, bridge rectifiers, and to provide controlled reverse polarity protection.

The Z4KE130-E3/73 is often used in regulated switched-mode power supplies, where it is used to dim the current flow. This prevents high currents from damaging the other components in the circuit. The Z4KE130-E3/73 is also used to control the speed of motors and to fulfill short circuit protection duties. It is an essential component in high-speed signal systems such as DC-DC converters, logic gate controllers, and interface circuits.

Working Principle

The Z4KE130-E3/73 consists of a single PN junction. It is a two-terminal device consisting of a cathode and an anode. When current passes through the diode, electrons drift in the reverse direction, generating a reverse current. This reverse current is limited to a safe level - the Zener voltage. The Z4KE130-E3/73 is designed to work in both directions, providing bidirectional protection from overvoltage and overcurrent.

When used in AC circuits, the Z4KE130-E3/73 acts as a rectifier, converting alternating current into direct current. This is achieved by allowing current to flow in one direction only and blocking current in the reverse direction. This regulation helps to protect other components in the circuit from damage due to overvoltage or overcurrent.

The Z4KE130-E3/73 is also used in voltage regulation circuits. This is done by allowing a small amount of current to flow through the diode at levels above the rated voltage. This reduces the voltage and helps to maintain a steady and consistent level.

The Z4KE130-E3/73 is an important component in many electrical circuits, due to its fast switching action, reliable performance, and wide range of features. Its ability to protect sensitive components from overvoltage and overcurrent, as well as to control the speed of motors, makes it an invaluable component in many electrical circuits.
