Types of TVS- Varistors, MOVs

TVS- Varistors, MOVs (Transient Voltage Suppression- Voltage Dependent Resistor, Metal Oxide Varistors) are a type of surge suppression device, designed to protect electrical and electronic systems from voltage transients created by lightning and other transient voltage events. They are typically used in power supplies, control systems, data processing, telecommunications, and other electrical systems where protection from surge voltages is critical. In addition, they can be used in industrial circuits and consumer applications, typically for locations where lightning or surge events are common.

V300LA20CP Application Field and Working Principle

The V300LA20CP is a voltage-dependent resistor (VDR) type of transient voltage suppression (TVS) device. It is designed for general purpose protection against transient voltage surges in low voltage AC and DC applications. This device is available in a TO-220 package and provides up to 300V of surge protection. It has a UL 94V-0 flammability rating and an operating temperature range of -40°C to 85°C.

The V300LA20CP works by controlling the surge current to a maximum value. When the incoming voltage reaches the device\'s "breakdown voltage" rating, the MOV will conduct and absorb the energy, limiting the voltage spike on the protected circuit. The MOV will extinguish when the incoming surge voltage has fallen below the breakdown voltage.

The V300LA20CP is suitable for a wide range of low voltage AC and DC applications, such as those found in power supplies, control systems, data processing, telecommunications, and other electrical systems. This device is also suitable for use in industrial circuits and consumer applications, particularly in locations where lightning or surge events are common. In addition, the low power design allows for the use of this device without having to add additional heatsinking.
