TVS - Varistors, MOVs are devices designed to safely absorb, or "clamp", a certain amount of electrical energy for the protection of the other elements of a circuit or system. One of such devices is VDRH20X115BSE.

VDRH20X115BSE belongs to the VDR series of protection devices, which are designed to provide protective semiconductor elements with superior surge absorption capacity. The specific model VDRH20X115BSE has a peak power of 115A. It is an ultra-small bidirectional protection device with an operating temperature ranging from -55°C to 130°C.

The working principle of VDRH20X115BSE is based on the principle of a voltage dependent dielectric. When a transient surge occurs, the voltage across VDRH20X115BSE increases and a dielectric material is formed between two metal electrodes. This material acts as a resistor between the two electrodes, reducing the voltage across them. When the surge voltage decreases, the dielectric material dissipates and the device returns to its normal operational state.

VDRH20X115BSE devices can be used in a variety of systems and applications, including automotive electronics, power supplies, telecom equipment, and industrial systems. They can be used to protect against surges created by switching operations, electrical noise, lightning strikes, and other transients. VDRH20X115BSE devices provide overcurrent protection, line regulation of voltages, and high-speed signal clamping.

VDRH20X115BSE devices are suitable for a variety of topologies, including: linear, flyback, forward, bridge rectifier, and buck-boost. The device can be used in systems with AC or DC input voltage, from 200 volts up to 1500 volts. They are also compatible with ESD protection, and have a low-clamping voltage of less than 10 volts.

In conclusion, the VDRH20X115BSE is an ideal device for providing efficient over-current protection from surges and transients. The device is highly reliable and is suitable for a wide range of topologies and applications. It can be used to protect against transient surges caused by switching operations, electrical noise, and lightning strikes. Its compact size and low-clamping voltage make it perfect for a variety of applications, ranging from automotive electronics to industrial systems.
