TVS - Diodes

TVS Diodes are devices used to provide protection against electrical transients and are used in a wide range of applications. The ATV04A131JB-HF is a specific TVS Diode designed for protection against both over voltage and over current conditions. It is a Bi-directional devices that arecharacterized by their low leakage, low capacitance, and fast response times.

Application Field of ATV04A131JB-HF

ATV04A131JB-HF is a low capacitance TVS diode used for protection from electrical transients and ESD (Electrostatic Discharge) such as lightning strikes, electrical surges, and voltage spikes. It is widely used in automotive, consumer, medical, and industrial applications. It is also used in integrated circuits and other sensitive electronics where fast response times and low leakage current are required. It is commonly used for protection of data lines, power lines, and control inputs/outputs.

Working Principle of ATV04A131JB-HF

The ATV04A131JB-HF is a Transient Voltage Suppression (TVS) Diode which works by clamping, diverting, and dissipating transient energy away from the protected device. It is a two-terminal device consisting of a reverse-biased Zener diode in series with a Uni-directional thyristor (SCR). When a transient voltage is applied, the Zener diode conducts the necessary current to trigger and hold the SCR on, thereby diverting the energy away from the protected device. Once the transient has been dissipated, the SCR is turned off. The ATV04A131JB-HF is designed to clamp the voltage to a safe value, as well as dissipate the energy of transients, thus providing protection to the device.

Conclusion

The ATV04A131JB-HF is a TVS Diode designed to provide protection for automotive, consumer, medical, and industrial applications from overvoltage and overcurrent electrical transients. It has a low capacitance and fast response time, and works by clamping and diverting transient energy away from the protected device. This makes it an ideal choice for sensitive electronics and integrated circuits, as well as data lines, power lines, and other I/O points in automotive and industrial applications.
