Transient Voltage Suppressors (TVS) are electrical components used to protect from voltage spikes and transients. The ATV04A151JB-HF is a TVS diode used for transient voltage protection.

Atv04A151JB-HF is a lead-frame, two-electrode, bidirectional over voltage suppressor, providing good transient overvoltage protection. It is housed in a J-Bend package type and suitable for automatic insertion. The constructions provide over voltage solutions with unidirectional or bidirectional protection with excellent electrical characteristics in comparison with similar sized components.

The operational characteristics of the ATV04A151JB-HF include a Peak Power of 500W, a Standoff Voltage of 15V, a Lightning strike of 8A 20µs, and a Clamping Voltage of 30V. With a Maximum Reverse leakage current of 150µA, a Reverse Standoff Voltage of 15V, and an average Current of 9.5A, the ATV04A151JB-HF serves as an efficient TVS diode.

The ATV04A151JB-HF provides a wide range of protection for low and high surge applications, offering a very low offset voltage and a significant reduction in surge power. The surge is dissipated as waste heat, thus reducing the need for cooling for a range of high power applications. The ATV04A151JB-HF also offers a high level of immunity from external interference such as high frequency pulses and low-level irregular pulses.

When a surge voltage is equal to or higher than the Standoff Voltage of ATV04A151JB-HF (which is 15V), the diode will activate. As the current passes through the diode, it produces a voltage drop across it, thus limiting the rise in voltage. When the surge voltage rises above the Clamping Voltage (which is 30V), the diode will limit the voltage incursion to the Clamping Voltage. This is because the diode “clamps” the surge voltage reducing it to the Clamping Voltage.

The ATV04A151JB-HF provides excellent protection for a range of systems from TV and audio equipment to computers, routers, and other electrical and electronic components. The diode is capable of providing excellent transient protection while consuming minimal power. Its small size also makes it ideal for mounting in places where space is limited.

In conclusion, the ATV04A151JB-HF is a reliable and efficient TVS diode designed to protect various electrical components from transient voltage spikes and transients. With its low offset voltage, high surge tolerance, and low power consumption, the ATV04A151JB-HF is a great solution for providing reliable protection for a variety of electronic devices and systems.
