TVS - Diodes

TVS or Transient Voltage Suppressor is a passive device used to protect sensitive electronic components from high-voltage transients and electrical overstress. TVS diodes are often used in combining both ESD and surge clamping protection in a single device. They are used in a variety of electric and electronic systems, such as power supplies, data lines, and RF transmission lines.

ATV04A8V5J-HF is just one type of TVS diode. It features a breakdown voltage of five volts, a high surge capability, and a very low leakage current, making it ideal for protecting sensitive electronic components from high-voltage transients and electrical overstress. ATV04A8V5J-HF has a wide range of applications including replacing zeners, and protecting high-speed data lines, AV cables, digital signal lines, LAN cables, and computer cables from damage due to ESD or transients.

Application Field and Working Principle of ATV04A8V5J-HF

ATV04A8V5J-HF is designed to protect high speed data and network cables as well as sensitive electronics that have short circuit or over-voltage protection needs. For this application, TVS diodes are generally preferred to protect against transients over ESD protection. ATV04A8V5J-HF protects the cable from high voltage transient and ESD surges. The Peak Pulse Current (IPP) is the amount of current it can take before it becomes damaged. It is typically determined by the total capacitance of the connected circuit. The breakdown voltage of ATV04A8V5J-HF is 5 volts which means that it can absorb more energy before it breaks down.

At electrical overstress or high-voltage transients, the TVS diode will limit the voltage at the connection point to a safe level, allowing the device to remain operational. The TVS diode acts as a short circuit from the overvoltage ground to the power source line and absorbs the energy of the transient. This balancing of energy places a clamp on the voltage at the connection point and a safe level of current is allowed through.

ATV04A8V5J-HF has a low clamping voltage of 8V and a very low leakage current, making it ideal for protecting sensitive electronics from high-voltage transients. The TVS diode is a cost effective solution for overvoltage protection, capable of protecting devices from up to 5kV of transients.
