Transient voltage suppressors (TVS) are widely-used devices for protecting electronic circuits from voltage spikes (voltage surge). They are generally composed of varistors, metal-oxide varistors (MOVs) and gas-tube arrestors. In this article, we will discuss the application field and working principle of VDRS10P150TME, an MOV designed by Vishay Semiconductor.

Application field

VDRS10P150TME is a varistor specifically designed for AC line protection. It is suitable for applications such as lighting systems, air conditioners, and household and office appliances. It is also used in LED lighting and other switch-mode power supplies (SMPS) equipment. It can provide over-voltage protection by suppressing voltage spikes from the source and passing them through its dissipation element without causing damage to the system. Moreover, it is resistant to over-temperature and overload, making it an excellent choice for protection against potential damage to your electronic devices or equipment.

Working principle

VDRS10P150TME contains a metal-oxide varistor element, which acts as a variable resistor. When an over-voltage occurs, the device can quickly conduct and the voltage is diverted away from the protected circuit. It works in a similar way to a fuse, in that it diverts the current away from the circuit, and the device is able to handle large over-voltage surges without damaging the circuit. The MOV element has a voltage-dependent resistance, meaning that as the voltage increases, the resistance decreases, allowing for fast switching between current and no-current states. In addition, the device also has two terminals that are connected to ground, thereby providing further protection against over-voltage transients.

In conclusion, VDRS10P150TME is an MOV specifically designed for AC line protection applications. It can provide surge protection by suppressing voltage spikes from the source and passing them away to the dissipated element, which helps protect the system from potential damage. It also features over-temperature and overload protection, making it an excellent choice for electronic devices and equipment.
