Transient voltage suppressors (TVS) are semiconductor devices designed to provide protection against damaging transient voltages, spikes, or electrical pulses. TVS can be unidirectional or bidirectional, depending on the application. One specific type of TVS is the V300LS20APX2855. This article will explore the application field and describe the working principle of the V300LS20APX2855.

Application Field of the V300LS20APX2855

The V300LS20APX2855 is a 300W unidirectional surge protector, designed for use in AC/DC, DC/DC, and AC line environments. It is suitable for use in a variety of applications, including automotive, telecom, PC, consumer electronics, and industrial. This device is compliant with the RoHS European Union (EU) Directive 2002/95/EC and is UL recognized.

The V300LS20APX2855 has been designed for use in system environments with strict voltage and energy requirements. Its ESD protection rating is lower than conventional surge protectors, so it can be used in applications that require a smaller form factor. Additionally, this configuration has proven to be capable of withstanding higher-level transients, and is capable of suppressing transient events up to 12 kV contact.

Working Principle of the V300LS20APX2855

The V300LS20APX2855 is constructed using a wide variety of components, such as transistors, capacitors, and resistors. The main function of the device is to absorb excess energy from transient voltage events. When voltage transients occur, the device responds by providing a path for the excess energy to be diverted away from the protected device.

The device works by controlling the current through the internal components and creating a low impedance path to the system ground. This low impedance path helps to reduce the voltage transient by providing a temporary voltage sink during transient events. Additionally, the device limits the impedance of the protected device by minimizing the rise time and duration of the voltage spike.

The device is also capable of providing fault protection, by sensing when the output voltage has exceeded the predetermined limit. Once the output voltage exceeds the threshold, the device will react by providing a fault indication to the system. This fault indication will alert the user that a transient has occurred and enable corrective measures to be taken.

In addition to providing fault protection, the device also provides ESD protection, by creating a low impedance path to the ground. The low impedance path provides a path for the ESD energy to be safely discharged, which prevents the protected system from being damaged.

The V300LS20APX2855 is a unidirectional overvoltage protection device, designed to provide protection against voltage transients, ESD, and faults in a wide range of applications. The device is constructed using a wide variety of components, which helps to both limit the rise time and duration of voltage transients, and provide fault protection.
