TVS (Transient Voltage Suppression) devices are an important part of many electrical systems. They are used to protect against transient surges that can cause electrical damage and destruction. Varistors, Metal Oxide Varistors (MOVs), and Thermal Response Varistors (TRVs) are all types of TVS devices. The V625LA10PX2855 is a varistor-type device that has a wide range of applications and uses.

Applications

The V625LA10PX2855 is a low-profile varistor designed to protect against intense transient voltage spikes in electronic systems. It has a wide variety of applications, including as a surge protector in AC/DC systems, as well as for overvoltage and inductive kick protection. Its small size makes it ideal for applications where space is limited, such as in laptops and cell phones. Other applications include automotive ECUs, LEDs, circuit protection for remote control receivers and relays, and AV equipment.

Working Principle

The V625LA10PX2855 is a metal oxide varistor (MOV) that works on the principle of electrical conduction. When an electrical current is applied to the device, its metal oxide material changes resistance in response to the voltage across it. This changing resistance acts as a barrier between the source and the load, preventing excessive current from being transferred and protecting sensitive electronics.

The device is composed of two metal electrodes separated by a layer of zinc oxide. When the voltage across the electrodes rises above a certain threshold, the zinc oxide material becomes an electrical conductor and begins to dissipate heat. This heat dissipates the excess energy and prevents it from reaching the load, thus effectively protecting it from any damaging effects. The varistor then reverts back to its non-conductive state when the voltage drops back below the threshold.

Specifications

The V625LA10PX2855 has a wide operating range of 52V to 550V, making it suitable for a variety of applications. It has a peak pulse power rating of 630W and a response time of less than 20 ns. The varistor is available in an epoxy-encapsulated package size of 28.5 x 25.5 x 4.2 mm. It is also RoHS compliant and is UL recognized.

Conclusion

The V625LA10PX2855 is a low-profile varistor designed for use in a variety of electronic applications. It has a wide operating range, a peak pulse power rating of 630W, and a response time of less than 20ns. Its small footprint and RoHS compliance make it an ideal choice for applications where space and environmental regulations are a concern. With its wide range of applications and features, the V625LA10PX2855 is an excellent choice for providing electrical protection in a variety of AC/DC systems.
