TVS - Diodes are among the most versatile components in power electronics. They are deployed in various applications to protect sensitive devices, reduce losses or to monitor certain functions.The ATV02W160B-HF is a unidirectional TVS Diode designed to protect against the effects of high-energy transients such as lightning, suppressor or line spikes. It is designed to handle up to 160A of surge current.

The intended application field for this device is to protect low-power DC circuits from dangerous short-circuit transients. Common applications include connecting components in consumer electronics, automotive, industrial, and various other applications where a high current transients could improperly disturb the operation of the device.

The core of the ATV02W160B-HF is made up of two active parts, a diode and an array of strap-diodes. This combination ensures a continuous and stable current flow when no transient occurs and a rapid clamping of current flow when a high-energy transient is detected.

The ATV02W160B-HF working principle is based on the idea of active clamping. Active clamping is a protection technique in which the device actively clamps the maximum peak current of an incoming transient to a safe level. This is done by connecting the device across the protected circuit. When a transient surge is detected, the diode and the strap-diode array activate and clamp the current to a safe level and the excess energy is dissipated to the ground itself. This helps protect sensitive components and reduce losses indefinitely.

The ATV02W160B-HF also features a low capacitance of 33pF. This allows the device to protect very small signal and data lines against ESD transients. The TVS diode also features a fast response time of 15ps enabling it to clamp very high peak current transients quickly and efficiently.

The ATV02W160B-HF is ideal for use in low-power DC circuits as it can handle large amounts of energy and clamp current to safe levels. With its fast response time and low capacitance, the device is able to protect circuits against dangerous transients. This makes it ideal for use in consumer electronics, automotive, and industrial applications.
