Varistors are the most common form of TVS - Transient Voltage Suppression diode. V481HG34 is a varistor designed to protect electronic devices from voltage overshoots or spikes. It is specifically designed to provide protection to very high voltage overshoots and fast transients.

Varistors are also known as Voltage Dependent Resistors (VDR). They are semiconductor components with a high-resistance value that is temperature dependent and decreases with voltage. They have a simple construction and can be used to protect components from damage caused by over-voltage transient spikes.

The V481HG34 is a 2-terminal ceramic varistor with a rated working voltage of 600VAC and a peak transient surge of 8kV. It is designed to provide protection to high voltage transients and overvoltages. Its designed peak current is 8kA, which makes it ideal for high surge currents. The device has a fast response time and can absorb high surge energy due to its low capacitance.

The working principle of a varistor is quite simple. It is essentially a diode with its resistance value varying according with the applied voltage. The varistor has a negative temperature coefficient, which means that the change in resistance is more pronounced as the temperature increases. When the voltage drops, the varistor conducts current and acts as a low resistance pathway for it. In this way, overvoltage transients or voltage spikes are prevented from entering the circuit and damaging sensitive components.

The V481HG34 is commonly used in consumer electronics, such as television sets and DVD players. It is also used in industrial and automotive applications to provide surge protection for a wide range of circuits. Because of its fast response time and high surge capacity, it is often used in power supply circuits. It is also found in power-line surge protectors, providing protection to electrical equipment against lightning strikes or other forms of surges.

The V481HG34 has a number of features that make it a valuable component in protecting circuits from damage. Its small size makes it easy to use in tight spaces. It also features a low capacitance, allowing it to respond quickly to changes in the input voltage and absorb high surge energy. Finally, its low leakage current ensures steady power supply operation under high voltage transients.

The V481HG34 is a versatile and highly effective device used for surge protection and transient voltage suppression. Its low capacitance and fast response time make it the perfect choice for protecting circuits from overvoltages. The fact that it is small and easy to mount, and its low leakage current makes it an ideal choice for consumer electronics applications.
