TVS - Varistors, MOVs are both components designed to protect sensitive electronics from voltage spikes. The ERZ-V14D270 is an example of a TVS-Varistor used to protect appliances, equipment, and other components from power surges, and it is available in a various sizes, making it a popular choice for many applications.

ERZ-V14D270 Application Field and Working Principle

The ERZ-V14D270 is a bidirectional, Transient Voltage Suppressor (TVS) varistor device that comes in a 14-pin DO-214AA package. It is designed to protect electronic components from drastic power surge voltages that can potentially cause equipment malfunction, failure, and even lost data. It is often used in electrical equipment, automotive systems, computers, and consumer electronics.

The ERZ-V14D270 Rated Voltage is 14V, with an operating limits voltage of up to 24V. The operating temperature range is -55°C to +125°C and the peak pulse power is 500W. When installed correctly, the device is expected to meet IEC 61000-4-2 level 4 ESD requirements, making it useful in applications that require superior protection against electrostatic discharge.

When the device is energized, the functional operation remains the same. When a surge voltage exceeds the set ratings, the circuit is immediately opened by the ERZ-V14D270. This protects the electronic components from the surge damage. Once the voltage drops below the set specifications, the circuit closing process is repeated, the device is restored and the electrical equipment is returned to its original functioning state.

The device also helps to protect the system and its components from reverse bias and electrostatic discharge (ESD). The bidirectional capability of the device makes it a good choice for use in systems such as automotive, power supply and other electrical circuits. It also has a wide operating temperature range and a low leakage current, which makes it reliable and suitable for application in various fields.

The ERZ-V14D270’s working principle is based on the PTC thermistor phenomenon. When exposed to a high voltage, a self-resistive element is formed by the PTC thermistor which can act as a fuse and prevent further rise in power. By forming a link between the power supply lines the ERZ-V14D270 can limit the over-voltage and the current surge. Thus, it is also called a “current-limiting element.”

Overall, ERZ-V14D270 is a highly reliable and cost effective electrical protection solution for a variety of applications. It can protect sensitive electronic components from over-voltage, over-current and electrostatic discharges. The device has a wide operating temperature range and an excellent peak pulse power ratings.
