TVS - Varistors, MOVs are widely used in many industries. The V385LC40BP varistor is one of the most common types used, and it has a wide range of applications. In this article, the V385LC40BP\'s application field and working principle are discussed.
The V385LC40BP is a radial leaded metal oxide varistor (MOV). It ranges from 5mm to 8mm in size and has a wide voltage range of 18V-385V. The V385LC40BP is used in many different applications, most notably in protecting sensitive electronic circuits from transient voltages or overvoltages. It limits the voltage to a safe level and prevents damage to a circuit board or other components.  
The V385LC40BP is designed for surface-mount mounting on PCB boards, and its height of 5mm makes it ideal for installations in a confined space. The V385LC40BP has a high surge current rating, meaning it can protect against large transient voltages or surges. It also has a low leakage current and a wide temperature range, making it suitable for a variety of uses. 
The working principle of the V385LC40BP is based on the physics of the varistor. A varistor is a voltage dependent resistor. Its resistance changes drastically when a certain voltage is exceeded. This change in resistance reduces the current in a circuit, thus protecting it from a transient voltage or surge. 
The varistor works by clamping the peak voltage to a safe level. When the voltage rises, the varistor will reduce or stop the current, protecting the circuit. The voltage at which the varistor begins to clamp is the so-called “clamping voltage”. The V385LC40BP has a wide clamping voltage range, making it suitable for many applications. 
In summary, the V385LC40BP is a widely used metal oxide varistor that is designed for surface-mount mounting on PCB boards. It has a wide voltage range, a high surge current rating and a low leakage current, making it suitable for protecting sensitive electronic circuits from transient voltages or overvoltages. The varistor works by clamping the peak voltage to a safe level. This makes the V385LC40BP an important part of many different industrial applications.
