The ATV02W171B-HF is a TVS-Diode – an electrostatic protective device – which is manufactured and supplied by a company called Littelfuse Inc. The device is designed to protect sensitive electrical and electronic equipment from overvoltage transients. It is a two-terminal device with a working voltage range of 17V to 171V. The device features ESD protection which can handle surges up to 40A (8/20μs waveform) and is designed for high-frequency applications.
Application Fields
The ATV02W171B-HF is suitable for a variety of high-frequency application fields. These include telecom networks, high-frequency power supplies, power converters, switch-mode power supplies, and isolated power supplies. These type of devices are also widely used in high-speed data transfer applications such as peripheral ports, fiber-optic links, power lines, and data links. Another major application field for these type of devices is LED lighting applications, they are suitable for lighting fixtures operating at high frequencies.Working Principle
The ATV02W171B-HF is a voltage-clamping device, meaning it is designed to limit the voltage across a protected circuit to a safe level. The device works by connecting an avalanche diode across the main circuit, this forms a voltage-clamping circuit. When an overvoltage transient occurs, the avalanche diode begins to conduct, clamping the voltage to a defined level before it reaches the main circuit. This creates a steering current which flows through the connected conductor and into the diode, dissipating the surge energy. The device can also be connected across a power supply line to protect against voltage transients from external sources.Conclusion
The ATV02W171B-HF is an electrostatic protective device that belongs to the TVS-Diode family. It features ESD protection and is designed for high-frequency applications. Its application fields include telecom networks, high-frequency power supplies, power converters, switch-mode power supplies, LED lighting fixtures, and isolated power supplies. The device works by connecting an avalanche diode across the main circuit, this forms a voltage-clamping circuit which limits the voltage to a safe level. This device is a great solution for protecting sensitive electrical and electronic equipment from overvoltage transients.The specific data is subject to PDF, and the above content is for reference
