TVSs (Transient Voltage Suppressors) are protective components which protect sensitive electronic components from high voltage and fast transients. Varistors, also known as Variable resistors, and MOVs (Metal Oxide Varistors) are two of the most common types of TVSs. VA100018D400DL is a varistor type TVS, widely used in today\'s high power applications.

VA100018D400DL is a 400V 18mm metal oxide varistor which can help protect electronics from high voltage transients, surges, and lightning,etc. It also has a low response time which is very important in applications that rely on speed. In addition, VA100018D400DL has excellent clamping capability and can handle up to 2450A peak impulse current.

VA100018D400DL has many applications in a wide range of applicationsincluding communication equipment, industrial control, power systems, automotive power supply systems, consumer electronics, solar power systems, medical equipment, and new energy vehicles.

VA100018D400DL’s working principle is based on the basic nonlinear property of metal oxide varistors. When a surge or transient overvoltage occurs, the varistor first reduces the surge voltage to a low level by the resistance of varistor material. Then, the low voltage transmitted to the protected circuit is reduced to an even lower level. The current flowing through the varistor is limited to the rated current of the product, providing effective protection for the protected circuit.

VA100018D400DL uses a single chip, which is made of zinc oxide and other additives. When a high voltage is applied, the resistance of varistor material will decrease significantly, allowing it to absorb the surge energy and dissipate it into the environment without causing any damage to the electronic device. This helps protect the sensitive electronic devices from destructive voltage transients and helps improve the overall reliability of the circuit.

In conclusion, VA100018D400DL is a very useful and versatile varistor type TVS which can help protect sensitive electronics from surges and high voltage transients. VA100018D400DL’s working principle is based on the basic nonlinear property of metal oxide varistors. Its high resistance to high voltage and fast response time make it an ideal choice for a wide range of applications.
