The V275LA2 is a two-terminal AC and lineside surge protector device, designed to limit overvoltage in types of electrical and electronic systems. It is designed to protect against surges, transients, and spikes in a variety of applications, such as lighting, power, communication, computers, and security systems. The device provides an exceptionally high level of protection for a very wide range of voltages.

The V275LA2 belongs to the class of voltage-dependent surge protectors or TVS (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors), and ESDs (Electrostatic Discharge). It utilizes a unique combination of metal oxide varistors (MOVs), a pair of Zener diodes, and a capacitor for exceptional surge protection in AC and Lineside applications. This combination ensures superior protection from both transient and surge events in applications with wide operating voltage ranges.

The application field of the V275LA2 includes any application where surge protection is desired. It is especially suited for AC and lineside applications that are subjected to overvoltage surge events. It can be used in applications related to lighting, power, communication, computers, and security systems.

The V275LA2 works on the principle of redirecting the overvoltage energy to ground. It contains an MOV and a pair of Zener diodes, connected in series with a capacitor. The MOV is the primary protection component, and it controls the flow of current from its source when a surge or transient is present. As the voltage exceeds a certain threshold, the MOV rapidly turns on, providing a low Impedance path to divert the surge current to ground.

The Zener diodes are designed to protect against very high transient voltages. When the voltage rises above a certain threshold, the Zener diodes conduct, allowing the current to be diverted to ground. The capacitor is added to provide additional filtering. It helps prevent voltage spikes from reaching the ground and also helps stabilize voltage levels.

The V275LA2 also includes a heat sink to provide improved thermal management. The heat sink helps dissipate the heat generated from the MOVs, allowing the device to operate at higher ambient temperatures. It also helps prevent the device from going into thermal runaway, which can cause permanent damage.

The V275LA2 is an excellent surge protection solution for AC and lineside applications. Its combination of MOVs, Zener diodes, and capacitor provide superior protection from overvoltage spikes and surges, making it an ideal in a wide range of applications. The addition of a heat sink ensures the device operates over a wide temperature range and can dissipate the heat generated from the MOVs.
