TVS (Transient Voltage Suppressor) diodes are commonly used for protection against electrical transients such as electrostatic discharges (ESD) or electrical surges. SMBG6.5AHE3/52 is a type of TVS diode, which is designed and certified to meet IEC61000-4-2, an international standard for ESD protection.

Application field:

The SMBG6.5AHE3/52 TVS diode is designed for ESD protection in harsh and dynamic environments. It is suitable for typical topologies such as DC-DC converters, audio circuits, automotive electronic modules, telecommunications systems, industrial automation and control systems, and digital consumer products such as TVs, laptops, and tablets. In addition, its low capacitance and fast response time make it suitable for high-speed data line protection, providing reliable protection for devices that are vulnerable to ESD.

Working Principle:

The SMBG6.5AHE3/52 TVS diode employs Zener-based ESD protection, which uses a reverse biased Zener diode with a diode-connected resistor to limit ESD voltage and dispose the surge energy to ground. The breakdown voltage of the Zener diode is carefully selected to provide maximum efficacy against various levels of ESD, while the resistor ensures that the TVS diode does not latch up and remains in a low impedance state during an ESD event.

The TVS diode also features lightning protection, which utilizes a low impedance P [N] junction to reduce the voltage and flow of leakage current to ground. The moveable P [N] junction is able to capture a broader range of energy, eliminating the need for multiple TVS diodes with different breakdown voltages to provide full-spectrum ESD protection. Because of this feature, the SMBG6.5AHE3/52 TVS diode is the ideal solution for high-voltage applications that require reliable ESD protection.

Conclusion:

The SMBG6.5AHE3/52 TVS diode is an ideal solution for applications that require reliable ESD protection. Its Zener-based protection and lightning protection capabilities provide comprehensive, robust ESD protection in harsh and dynamic environments. It is suitable for topologies such as DC-DC converters, audio circuits, telecommunications systems, and more. In addition, its low capacitance and fast response time make it suitable for high-speed data lines.
