TVS - Varistors, MOVs Application Field and Working Principle

TVS (Transient Voltage Suppressors) is a passive component used for protecting the system from electrical overstress, such as electrostatic discharge, lightning surge, and power-crossing. MOVs (Metal Oxide Varistors) are TVS components that provide the highest level of protection for sensitive electronic devices, such as sensors, controllers, and circuit boards. The V47ZC05PX2855 is a standard surface mount, high-temperature, TVS diode that provides bidirectional ESD protection, and is suitable for all types of systems that require ESD protection.

The V47ZC05PX2855 is designed to provide a high dynamic resistance to voltage spikes. It is constructed with a ceramic body, Zener diode, and epoxy-filled chamber. The ceramic body provides mechanical strength and resistance to environmental conditions such as temperature, moisture, and corrosion. The Zener diode provides high voltage clamping and low impedance for ESD protection of the sensitive components in the system. The epoxy-filled chamber protects the Zener diode from damage caused by ESD events.

The V47ZC05PX2855 has two modes of operation. The first mode is a unidirectional clamping of the transient voltage spike. This mode is used when a very low overshoot, such as electrostatic discharge, is present. The second mode is bidirectional clamping. This mode is used when a high overshoot, such as a lightning surge, is present. In both modes, the V47ZC05PX2855 provides a high dynamic resistance to protect the system from voltage spikes.

The V47ZC05PX2855 is commonly used in industrial, automotive, and consumer electronics, such as tablets, smartphones, and laptops. It is capable of handling a wide range of currents in reverse direction, as well as suppression voltage up to 28V. This device is designed for use over the full temperature range from -55°C to +125°C. This makes it an ideal solution for applications that require a wide temperature range operation.

The working principle of the V47ZC05PX2855 is simple yet effective. During an overvoltage event, the V47ZC05PX2855 acts as an electronic clamp, allowing current to flow through it but limiting the voltage to a specified level. This prevents the transient voltage spike from exceeding the specified voltage threshold and damaging the sensitive components in the system. The V47ZC05PX2855 provides both bidirectional and unidirectional protection, making it an ideal solution for protecting against ESD and lightning surges.

The V47ZC05PX2855 is an effective TVS component for protecting sensitive electronic devices from electrical overstress. It provides a high dynamic resistance to voltage spikes, and is designed for use over a wide temperature range. Its simple yet effective working principle makes it ideal for applications in industries such as automotive, industrial, and consumer electronics.
