TVS, or Transient Voltage Suppressors, help protect circuits from sudden voltage spikes which can damage or even destroy electronic components. They are commonly used to protect electronic circuits from lightning strikes or power surges, and in industrial and automotive applications. When designed properly and in the right environment, they can provide reliable protection against over-voltage and transients. One of the most popular TVS devices is the VDRH05E320BKE. This article will explain the application field and working principle of the VDRH05E320BKE.

The VDRH05E320BKE is an axial leaded Varistor, or Voltage Dependent Resistor. It is designed to protect sensitive electronic components from both high and low voltage transients that can cause damage. It features high peak power absorption, a low clamping voltage, and excellent surge protection capabilities. This Varistor is particularly suited for applications such as automotive systems, computers, medical device, industrial instrumentation, and telecommunications, as well as home appliances, equipment, and lightning protection.

The VDRH05E320BKE works in two ways. First, it dissipates energy in the form of heat by clamping the voltage spikes to an acceptable level. To achieve this, the Varistor contains special metal-oxide varistors, or MOVs, which act like a semiconductor diode. The MOVs provide a path for the electric current to flow through, and when the voltage exceeds theVaristor’s rated voltage, the MOVs become conductive and clamp the voltage. Basically, they act like electronic shock absorbers to dissipate voltage spikes.

The second way that the VDRH05E320BKE works is as a current limiter. This is done through a Zener diode. The Zener diode limits the amount of current that is able to flow through the device during an over-voltage situation. By limiting the current, it allows the Varistor to safely dissipate the voltage spikes without experiencing dangerous levels of current.

The VDRH05E320BKE is a high performance Varistor that can easily handle high peak power absorption and provide excellent surge protection. It is a reliable and cost effective choice for applications such as automotive systems, computers, medical device, and industrial instrumentation, as well as home appliances, equipment, and lightning protection. Additionally, its low clamping voltage and current limiting capabilities make it especially effective in protecting sensitive components and systems from voltage spikes.
