TVS diodes are a range of surge protection devices which offer superior protection for high voltage applications. The LCE28 series of TVS diodes are designed to safely absorb high voltage and communication-level impulses and are an important component in protecting sensitive electronic equipment. This article examines the application fields and the working principle of the LCE28 series of TVS diodes.

Application Fields

The LCE28 series of diodes are well-suited for a variety of applications, including a range of communication, automotive, and consumer electronics applications. They can be used in any application where the protection of high voltage electronic circuits from over-voltage or surge related events is required.

• Communication Applications: The LCE28 diodes are designed to provide robust protection for telephone and communication devices, including telephone line over-voltage protection, digital communication lines (E1/T1), ISDN, ATM, UTP/TCP, WAN and VoIP (Voice over Internet Protocol) devices.
• Automotive Applications: The LCE28 diodes are also effective in automotive applications, such as the in-vehicle infotainment systems, powertrain systems, and on-board diagnostics systems.
• Consumer Electronics: The LCE28 series of diodes provide superior over-voltage and surge protection for a range of consumer electronics, such as mobile phones, tablets, laptops and other portable electronic devices.

In all of the applications mentioned above, the LCE28 series of TVS diodes are designed to safely absorb high voltage and communication-level impulses, ensuring that the sensitive electronic equipment is protected from damage. The diodes are also designed to ensure that the system is able to withstand static discharges and varying high voltage transients, resulting in improved system safety and reliability.

Working Principle

The primary function of a TVS diode is to provide transient suppression for high voltage signals. The LCE28 series of TVS diodes operate in a similar fashion, using a combination of avalanche breakdown and non-linear resistance to limit the voltage of a circuit. The most common application of these diodes is to protect circuits from over-voltage transients.

When exposed to a high voltage transient, the TVS diode will turn on, providing a short-circuit path for the excess voltage. This quickly reduces the voltage of the circuit, protecting the sensitive electronic components from damage. As soon as the voltage is reduced to a safe level, the diode will turn off again, allowing the circuit to continue functioning as normal.

The selection of the correct TVS diode for a particular application is critical for ensuring effective protection of the system. The LCE28 series of TVS diodes offer superior performance, with their ability to safely absorb high voltage and communication-level impulses, allowing them to protect sensitive electronic equipment from damage.

Conclusion

The LCE28 series of TVS diodes provide superior over-voltage and surge protection for a range of high voltage applications, including communication, automotive, and consumer electronics applications. By utilizing a combination of avalanche breakdown and non-linear resistance, the diodes are able to quickly reduce high voltage transients and protect sensitive electronic components from damage. The LCE28 series of TVS diodes is an ideal solution for superior transient protection in a variety of applications.
