TVS (Transient Voltage Surge Suppressor) is an integral part of any electronics system and its principal components encompass varistors, metal oxide varistors (MOVs), diodes, as well as other active circuit elements such as thyristors and transistors. Specifically, a TVS device such as the VE13M01750KED is designed to protect low voltage electronics circuits from electrical transients caused by lightning strikes, power outages, or even electrostatic discharge.

Application Field of VE13M01750KED

The VE13M01750KED is a 3-pin single-phase TVS diode designed for robust transient voltage protection of low voltage lines in AC applications. It is particularly suitable for applications where Data Line Protection (DLP) is required to comply with Class I & II regulatory standards. This includes a variety of consumer, commercial, and industrial products, such as computers, printers, televisions, sound systems, appliances, vending machines, lighting, lithium-ion batteries, etc. The VE13M01750KED is also suitable for telecommunications systems, as well as automotive, naval, and aerial systems.

The VE13M01750KED is designed for typical 8 kV contact discharges and 30 kV air discharge, making it one of the most robust TVS devices on the market. It is capable of handling transients exceeding ±40V which allows it to protect against a wide range of transient voltages. Furthermore, its high peak power capability and low leakage current make it an ideal choice for applications where short-term transients must be rapidly suppressed without compromising the current carrying capacity of the device.

Working Principle of VE13M01750KED

The VE13M01750KED is based on a metal-oxide varistor (MOV) architecture, which allows it to provide robust transient protection. Essentially, a varistor is a non-linear device composed of ceramic material with a high dielectric strength, which makes it the perfect element for suppressing transients. When a transient voltage spike is present, the MOV exhibits a very low resistance, which allows it to suppress the voltage and thus protect the connected circuit.

The VE13M01750KED incorporates two MOVs connected in series, which allow it to provide superior protection against transient overvoltages. The series connection also allows the device to provide protection even when one of the MOVs fails, which increases its reliability. The device is also designed with a capacitor which helps keep the discharge transient voltage below the breakdown voltage.

In addition to offering protection to the connected circuit, the VE13M01750KED also helps prevent formation of excessive power surges which can result from the failure of an electronic component in the connected circuit. This helps increase the overall reliability and safety of the connected system.

Conclusion

The VE13M01750KED is an ideal choice for applications where Class I & II DLP regulatory requirements are needed. One of the key advantages of the device is its robust transient protection, which is facilitated by its MOV-based architecture. The dual MOV connection and the presence of the capacitor also contribute towards its superior protection capabilities. Finally, its high peak power capability and low leakage current help prevent power surges, which again benefits the overall reliability and safety of the connected system.
