TVS - Varistors, MOVs, are designed to protect circuits against voltage transients. An example from this category is the V680LA80APX2855. This type of protection component is a metal oxide varistor (MOV) with the peak current rating of 68A (8/20μs) and it is designed to divert transient surge current away from sensitive components.

The V680LA80APX2855 has a wide range of applications. It is especially suitable for use in DC power lines, and also suitable for power supplies or systems with conditions such as short-circuit, overvoltage and surge, especially in places where it is important to maintain the power continuity. For example, when a DC motor is suddenly started, the current is up to several times the rated current, and the MOV can effectively reduce the impact of the surge or overvoltage.

In terms of its working principle, the V680LA80APX2855 is essentially a non-linear resistor that can dynamically adjust its resistance according to the input voltage. It consists of a semiconductor material, commonly zincoxide or antimony-doped (Sb-doped) zinc oxide. This material exhibits nonlinear conduction characteristics under certain conditions, such as increasing resistance with the intensity of the current. When a voltage pulse is present, the resistance of the MOV becomes small enough so that the current can flow freely through it, thus diverting the surge current away from sensitive circuits.

The V680LA80APX2855 is an ideal protection element due to its wide operating temperature range (-55°C to +125°C) and fast reaction time (less than 1nS). It is designed with lead and lead-free termination options, and it has a maximum clamping voltage of 630V. The V680LA80APX2855 is also RoHS-compliant, making it a great choice for energy-saving equipment.

In conclusion, the V680LA80APX2855 is an ideal protection element for DC power lines, power supplies, and systems which need to maintain power continuity. Its wide temperature range and fast response time make it a great choice for energy-saving equipment. With a maximum clamping voltage of 630V, this product is suitable for use in many different applications.
