TVS - Diodes: JAN1N6122 Application Field and Working Principle

Transient voltage suppression (TVS) diodes are devices specifically designed to protect electronic circuits from electrical overstress damage caused by voltage transients that exceed the normal operating voltage range of the system. The JAN1N6122 is a tri-bi diode designed to provide protection from ESD, EFT, and lightning transient events.

Applications of JAN1N6122

The JAN1N6122 is a high-voltage, high-power rectifier diode with an operating junction temperature range of -65°C to +175°C. It can be used in a variety of applications, including power conditioning and current limiting, computer and telecom protection, Industrial Automation Equipment, Automobiles, and Energy Storage Systems. The diode also provides protection against high-voltage transients in communications, sensing, control, and protection circuits.

Working Principle of JAN1N6122

TVS diodes are commonly used in reverse bias to protect against electrostatic discharge (ESD), electrical fast transients (EFT), and lightning transients. The JAN1N6122 utilizes a unique tri-bi configuration that makes it different from other varieties of TVS diodes. This allows it to handle large transients up to 26 kA without failure. It also has an exceptionally low leakage current for sustained power applications and provides excellent clamping characteristics for ESD and EFT transients.

When a transient event occurs, the JAN1N6122 quickly responds and the internal diodes break forward, forming a low-impedance path from the transients source to ground. This limits the amount of energy that is delivered to the protected circuit, preventing it from becoming damaged. The device also features a soft recovery characteristic, providing increased system reliability while reducing the stress on other circuit components.

Advantages of JAN1N6122

The JAN1N6122 provides superior protection from high-voltage transients in a small footprint. It offers excellent clamping performance, ultra-low leakage current, and a rapid response time. The device also has an ESD rating up to 28 kV, making it one of the most robust TVS devices available. Furthermore, the device is RoHS compliant and does not require any external components for protection.

In addition to its robust protecting capabilities, the device also features a reduced power dissipation for increased efficiency. The JAN1N6122 is also designed to ensure a reliable connection when used in conjunction with board-to-board shields, eliminating the need for additional hardware.

Conclusion

In conclusion, the JAN1N6122 is a high-voltage, high-power diode designed to provide protection from ESD, EFT, and lightning transients. The device features a tri-bi configuration that allows it to handle large transients up to 26 kA without failure. It also provides superior protection from high-voltage transients, excellent clamping performance, ultra-low leakage current, and a rapid response time. Furthermore, the device features a reduced power dissipation and is RoHS compliant, making it a highly reliable and cost-effective choice for protection applications.
