TVS (transient voltage suppressors) refer to devices able to protect circuits from voltage transient events. Their presence inside the circuit causes the voltage to be diverted from a certain value to a lower value. Varistors, MOVs, Steering Diodes and Silicon Avalanche Diodes (SADs) are all part of the TVS devices portfolio. Certainly, V480LS10PX2855 is also one of these devices. This article will explain understanding the application field and working principle of V480LS10PX2855.

V480LS10PX2855 application field

V480LS10PX2855 is a lead-free device that belongs to Radial Lead Varistors Class. It is especially conceived for protecting circuits from overvoltage transients due to inductive switching and lighting, transmitting over long lines and blocking peak impulses. It also makes a great protection from both high-level and low-level surges. In addition, this device has no polarity or mounting orientation, making it a very versatile component.

The specific type of V480LS10PX2555 VARS is approved by UL 1414 standard. This sets limits to maximum Clamping Voltage (VC) and impulse voltages (VI/VP). Furthermore, this device offers between 30 to 90V Operating Voltage (VO) and a maximum Clamping Voltage of 333V. With regards to environmental resistance, V480LS10PX2555 can be used in temperatures between -40 °C up to +125°C.

V480LS10PX2855 working principle

V480LS10PX2855 is based on a non-linear resistive characteristic, making the transient voltage diverted from a certain level to a more secure one. Specifically, when high-energy transient conditions occur, the metal oxide core of the varistor conducts this energy through the terminals, while maintaining the polarity. In a schematic representation, this devices induces low TOV between the supply and the electronic circuits, limiting the voltage in a secured value.

The dynamic responses of the device depend on the parameters of the energy source, such as amplitude, duration, frequency and impedance. These two polarities, combined with the internal junction capacitance of the V480LS10PX2555 varistor, generates a dynamic protection, which enables the device to shunt, too.

Conclusion

To sum up, V480LS10PX2855, as part of the TVS, is a Radial Lead Varistor designed to offer protection under a variety of conditions. This device is certified by UL 1414 standard, while offering 30 to 90V Clamping Voltage. Its working principle is based on a non-linear resistive characteristic, which limits the voltage to a certain value. In conclusion, V480LS10PX2555 is one of the eldest and most established devices in terms of protecting circuits from overwhelming voltage.
