TVSs, also known as Transient Voltage Suppressors, are devices that have been created with the intent of protecting electrical equipment from voltage transients and surges. Their functionality is to absorb excessive voltage peaks and divert them away from delicate components. Varistors, also referred to as Voltage Dependent Resistors (VDRs), are one type of TVS that is quite common today. The ERZ-VS34C361 is a common type of varistor that is used for both protective and post-protection applications.

The ERZ-VS34C361 has a nonlinear voltage-current characteristic with an excellent response time and typically operates in the VDRs region of between 5 and 45 Volts. The device has an integrated Zinc Oxide (ZnO) element, making it a very low-profile varistor with the ability to be mounted closer to the insulation of the device it is protecting. The ERZ-VS34C361 is used in a wide variety of electrical and electronic applications including, but not limited to: automotive panels, transportation systems, home-appliance control systems, home-appliance protection, industrial protection systems and LED lighting protection.

The working principle of the ERZ-VS34C361 is quite simple. When voltage is applied to the device, the ZnO elements inside the device will vary their resistance according to the voltage applied. The ZnO elements act as a variable impedance, allowing current to flow through the device when a transient surge occurs. This helps to divert the damaging current away from the protected device so that it is not damaged or malfunctioning. The ERZ-VS34C361 is designed to have a low internal capacitance, which allows it to react quickly enough to suppress the most severe transient surges.

In addition to the basic function of protecting against transient voltage surges, the ERZ-VS34C361 also provides back-up protection for sensitive devices and prevents over-voltage conditions from forming. This enables the device to remain operational even in the event of a surge or transient voltage event. The device also contains an integrated thermistor that is used to protect the device against overheating. The thermistor will cut off the power supply to the protected device in the event of a thermal overload.

Overall, the ERZ-VS34C361 is a highly versatile and reliable varistor with a wide range of applications. Its nonlinear voltage-current characteristics and low internal capacitance provide superior protection against transient voltage surges and over-voltage conditions. These features make the device suitable for a variety of applications including automotive panels, industrial systems, LED lighting systems, and home-appliance protection. The integrated thermistor also provides additional protection against short-circuits and overheating in the event of any kind of surge or transient voltage event.
