TVS - Diodes are essential components for protecting electronic systems from overvoltage transients, such as those caused by lightning. Among them, the MXLLCE100AE3 has become one of the most popular in the industry. Its application field and working principles are as follows.

Application Field

MXLLCE100AE3 is especially suited for protecting against high-energy surges that occur in high-end communications, gaming, automotive, and industrial systems. It is widely used in the following scenarios:

• Lightning strikes
• Power spikes
• Electrical surges
• Protection from powerful transients
• General voltage clamping tasks
• Secure operation of highly sensitive ICs

Moreover, it also finds its applications in high-temperature consumer and medical electronic equipment.

Working Principle

Essentially, the MXLLCE100AE3 is a voltage-limiting Zener diode. When the input voltage exceeds the device’s breakdown voltage (BV), the device will start to conduct, dumping the entire input voltage across itself. This helps protect the downstream circuit from potentially damaging voltages.

The MXLLCE100AE3 devices offer several benefits compared to other standard Zener diodes. They have an ultra-low sub-nanosecond response time and provide excellent protection from voltage transients and ESD. The devices also feature a high performance unidirectional diode layer and a special ESD and high-voltage protection layer.

Moreover, the device also comes with an integrated TVS diode, which helps reduce ringing on high-speed data lines. This ensures that data is accurately transmitted. The device also has an optional back termination feature for better performance with high-data-rate cables.

The MXLLCE100AE3 also features a high-level of temperature stability. This ensures reliable performance in harsh operating conditions and helps extend the life span of the device.

Conclusion

The MXLLCE100AE3 is a popular voltage-limiting Zener diode, offering excellent protection from high-energy surges. It features a unidirectional diode layer, a special ESD protection layer, and an integrated TVS diode. Moreover, it has a high level of temperature stability and an optional back termination for improved performance in high-data-rate cable applications. It is the perfect choice for protecting against overvoltage transients in high-end consumer and medical electronic applications.
