A diode is a device that is used to restrict current in a circuit so that electricity only flows in one direction. The Z4KE200AHE3/54 is a single Zener diode with a breakdown voltage of 200V. This type of diode quickly switches between a low-impedance forward conduction state and a high-impedance reverse breakdown state.

Application Fields

The Z4KE200AHE3/54 is typically used for voltage regulation, AC/DC isolation, signal switching, and rectification applications. Zener diodes are also used in applications such as power supplies, motor drivers, noise suppression, and overvoltage clamping. They are used to protect sensitive circuitry from high voltage transients caused by electrostatic discharge, lightning surges, and other disturbances.

Working Principles

Zener diodes are specially designed to operate in either the forward bias or reverse bias mode. When in forward bias, current flows through the diode body, allowing it to perform its intended task in the circuit. When in reverse bias, voltage builds up across the junction, and when the breakdown voltage is reached, current begins to flow through the diode, allowing it to regulate the voltage in the circuit.

The Z4KE200AHE3/54 zener diode has a temperature coefficient of +2.3mV/°C. This means that it can accurately regulate voltage even at extreme temperatures, making it an ideal choice for applications such as power supplies that are subject to fluctuations in temperature.

The Z4KE200AHE3/54 has a power dissipation of 2 W and is capable of withstanding a peak pulse current of 32 A. This high current rating allows it to be used in a wide variety of applications, including automotive, avionics, telecommunications, and lighting systems.

The Z4KE200AHE3/54 is RoHS compliant and comes in a TO-3P package. This package houses all of the necessary components (such as a substrate, an epitaxial layer, an anode, and a cathode) and allows it to be installed in a single device.

Conclusion

The Z4KE200AHE3/54 Zener diode is a versatile single device that is capable of voltage regulation, AC/DC isolation, signal switching, and rectification. It has a low temperature coefficient (+2.3mV/°C), a high peak pulse current rating (32 A), and a power dissipation of 2 W. Moreover, it is RoHS compliant and comes in a TO-3P package, making it an ideal choice for applications in automotive, avionic, telecommunications, and lighting systems.
