JANTX1N6128A Circuit Protection

TVS - Diodes

The JANTX1N6128A diode is an example of a Transient Voltage Suppressor (TVS) diode. A TVS diode is a high power diode that is designed to protect against electrical spikes caused by lightning or electrostatic discharge (ESD). TVS diodes are often used in telecommunications and other electronic equipment.

Application Field

The JANTX1N6128A is an ultra-high-performance, high-reliability, high-power TVS diode. It is designed for use in the protection of systems that are exposed to line or antenna lightning surges, EFT and ESD pulses. It provides reliable and repeated transient overvoltage protection for a variety of applications including communications CATV, broadcast, CATV-STB, wireless base station, optical network equipment and other industrial-control equipment.

Working Principle

When an overvoltage transient appears, the JANTX1N6128A conducts current, dissipating the energy to prevent excessive voltage from being applied across the protected components. The device operates in a nonlinear mode in order to clamp the voltage and avoid the destruction of the protected components. The device is designed to withstand high power surges of up to 11kA (8/20Ω surge, IEC61000-4-5 ed.2 compliance). The TVS diode also has excellent ESD protection, with the ability to withstand direct contacts up to 25kV (human-body model).

The JANTX1N6128A TVS diode is robust and capable of withstanding multiple transient spikes, and its small size is convenient for high-density mounting. The device is designed to be exposed to high power surges without die degradation, and it is certified to be compliant with safety and performance standards such as IEC-60898 and UL-497. It is also equipped with an off-state clamp voltage, which enables it to withstand high peak pulses without tripping the protection circuit.

Conclusion

The JANTX1N6128A TVS diode is a versatile and reliable device for providing protection against transient voltage surges. Its small size and high-power capability make it ideal for high-density mounting and applications requiring high-reliability protection. It has excellent ESD protection and is certified to comply with a variety of safety and performance standards, giving it the reliability to withstand multiple transient spikes and protect the system from excessive voltage.
