TVS - Diodes

TVS (Transient Voltage Suppressors) diodes are specially designed for providing electrical overvoltage (EOS) and electrostatic discharge (ESD) protection. 1N6271A-E3/54 is a unidirectional bidirectional TVS diode, which is designed to suppress transients on both sides of its supply voltage. The device has an operating voltage range between 7 to 250V, with a power dissipation capability of 500W at ambient temperature of 25°C.

1N6271A-E3/54 Application Field

The 1N6271A-E3/54 is suitable for a wide range of surface-mount applications including consumer electronics, information communications, power supplies, automotive systems and more. It is designed to protect systems from ESD, overvoltage or surge conditions. The device can be used to protect appliances such as washing machines, microwaves, TVs, and other household electronics from surges due to lightning strikes or power line outages. It is also useful for automotive applications, providing EMI/RFI immunity for ECUs, alternators, data bus components and more.

1N6271A-E3/54 Working Principle

When the voltage on the 1N6271A-E3/54 exceeds the breakdown voltage (7V to 250V), the diode conducts current in a single direction. The device limits the voltage on the node to which it is connected to a safe level. As the surge voltage exceeds the breakdown voltage, the diode quickly conducts the surge current. This limits the voltage on the node to which the diode is connected. The device offers excellent current handling capability under surge conditions, allowing the device to maintain the voltage on the node within the required safe limits.The device also offers excellent overvoltage, ESD, Electro-Static Discharge, Electrostatic Discharge, RFI, Radio-Frequency Immunity, and transient protection capabilities, with a faster response time than standard diode devices. It is also highly resistant to surge energies and provides a high resistance to corrosive elements, making it well suited for use in industrial applications. The device employs a heat-resistant polyimide (PI) base substrate material which is capable of handling a wide range of temperatures (up to 250°C). It also offers improved isolation performance and enhanced mechanical stability, while eliminating the need for complex and costly hardening schemes.

Conclusion

The 1N6271A-E3/54 can provide excellent overvoltage, ESD, electro-static discharge, electrostatic discharge, RFI, radio-frequency immunity, and transient protection for a wide range of applications. Its quick response time, high surge energies tolerance, as well as its heat resistance and highly stable mechanical design make it an ideal choice for industrial, automotive and consumer electronics applications.
