TVS - Diodes

MlJ60A is a transient voltage suppressor (TVS) diode used to protect electronic circuits and systems from transient high voltage and electrostatic discharge (ESD) problems. It is also used for surge protection and is designed to limit the voltage between its two ports. TVS diodes, when subjected to high voltage spikes, can safely dissipate them in the form of heat released to the circuit board as the voltage is clamped at a safe value. TVS diodes are widely used in various industries such as telecommunications, consumer electronics, automotive, and industrial control systems.

Principle of Operation

The TVS diode is a two-terminal device with the anode connected to the positive line and cathode connected to the negative line. When voltage across its terminals exceeds a certain value, TVS diode starts to conduct current. This is known as the clamping voltage or breakdown voltage and it is an important parameter for TVS diode selection.The current limiting capability of TVS diode comes into play when the voltage across its terminals exceeds the breakdown voltage. In this case, the TVS diode starts to conduct current as its internal resistance drops dramatically. This allows the TVS diode to limit the voltage and absorb the surge.

Applications

TVS diodes are widely used in electronics and telecommunications for overvoltage protection in applications such as ESD protection, surge protection, and power line protection. They can also be used for automotive applications such as spark plug surge protection, fuel injector surge protection, and ignition coil surge protection. In industrial control systems, TVS diodes are used to protect microprocessors, touchscreens, and controllers from high voltage transients.

Conclusion

TVS diodes are an important type of overvoltage protection device and are widely used in various industries. They provide both ESD and surge protection for a wide range of electronic systems and applications. The MSMLJ60A is a TVS diode with good ESD protection and current limiting capability and is suitable for various applications.
