TVS - Diodes are an integral component of any electrical circuit. They play an important role in providing protection against over-voltage, transients, and electrical interference. The LCE24A-E3/54 is a critical element in any application where reliable protection is required. It is a diode designed to provide fast response times for transient voltage suppression and other related applications. By understanding its application field and working principle, users can better identify and use it to properly protect their systems.

Application Field

For many applications, the LCE24A-E3/54 can provide a professional protection solution. This device is ideal to be used in power supply lines, telecommunication/LAN circuits, and over-voltage protection for industrial control systems. This component is designed for a wide working temperature range from -40℃ to +125℃, making it suitable to be used in a variety of harsh environments. It is also rated to provide minimum power dissipation of 500W, making it perfect for applications that require high power protection, such as lightning protection and load short circuit protection.

Working Principle

The LCE24A-E3/54 works through avalanche breakdown principle. When the voltage across the device increases, the built-in avalanche effect triggers and varies the diode’s impedance. This suppresses the transient voltage through a short reverse current, allowing the system to recover quickly with minimal damage.

The protection performance of the LCE24A-E3/54 can be adjusted using a series resistor to control the breakdown voltage of the device. When the transient voltage exceeds the breakdown voltage, the LCE24A-E3/54 works as a low impedance shunt to protect the circuit. At the same time, it can also be used as a slow trigger diode to absorb the energy from the noise source.

This device complies with the IEC 60747-5-2 standard and is certified to safety approval classes I and II. It is designed with a surge current rating of 24A, a breakdown voltage of 54V, and maximum withstand voltage of 150V.

The LCE24A-E3/54 is an excellent solution for providing reliable protection from over-voltage transients, lightning surges, and electrical interference in various electrical circuits. It is a versatile device that is designed to meet a variety of demands, making it a great choice for many applications.
