ATV50C181J-HF Circuit Protection

TVS - Diodes

A transient-voltage-suppression (TVS) diode is an electronic component, which is designed to protect other components from transients such as electrostatic discharge (ESD), electrical overstress (EOS), and lightning-induced surge events. In general, TVS Diodes will quickly clamp the voltage applied to the protected component to a predetermined safe level, allowing the protected device to operate without incurring any damage.

The ATV50C181J-HF is a high-speed, single-channel, unidirectional TVS diode specifically designed to protect sensitive electronics from overvoltage, high-energy transient and electrostatic discharge (ESD) events. This TVS diode is rated for operating conditions between -55°C and +175°C, with peak power dissipation up to 5.9W and peak pulse current up to 35A. It also features a unique “breakdown delayed” structure which substantially improves ESD performance.

Application Field

The ATV50C181J-HF is a general-purpose diode designed to offer high-speed protection for many different applications, such as automotive and industrial control circuits, telecom circuits, consumer electronics, and more. It can be used in many different types of applications, including automotive instrumentation, electronic switching systems, medical equipment, telecom systems, and any other areas where protection against transient voltage spikes is necessary.

Working Principle

The ATV50C181J-HF works by quickly clamping the voltage applied to the protected component to a predetermined safe level. The diode is capable of suppressing large transient overvoltage spikes, while minimizing the associated damage on the protected component. Additionally, the “breakdown delayed” structure of the diode reduces the ESD significantly, making it suitable for sensitive electronic systems.

When an overvoltage situation is detected, the ATV50C181J-HF will quickly respond, by clamping the voltage applied at the protected device to a safe level. This helps to ensure that the device remains functional, while preventing any damage that might be caused by the overvoltage spike.

The ATV50C181J-HF also features reverse breakover protection, which ensures that the internal circuitry of the diode will not be damaged in case of an inadvertent high voltage reverse polarity. It also features dual-sided hermetic metal seal to ensure reliable protection in case of a vacuum, moisture, or dust intrusion.

The ATV50C181J-HF is designed to offer a high degree of protection to sensitive electronic devices. The device is available in a variety of circuit packages, allowing it to easily integrate into existing electronic systems. Additionally, the diode’s high speed and low total capacitance make it suitable for a wide range of applications.

In conclusion, the ATV50C181J-HF is a high-speed, single-channel, unidirectional TVS diode specifically designed to protect sensitive electronics from overvoltage, high-energy transient and electrostatic discharge (ESD) events. It is a general-purpose diode, which is capable of quickly clamping the voltage applied to the protected component to a predetermined safe level, allowing the protected device to operate without incurring any damage.
