TVS Diodes

TVS Diodes are devices designed to limit the peak voltage, typically up to 30V, when subjected to large voltage transients. TVS diodes perform the same role as zener-based protection, but offer a much more effective solution. The MXLSMCGLCE90A is an example of a TVS diode.

Application Field

TVS diodes are commonly used to protect sensitive electronics from high voltage transients. Such as those caused by lightning, switch or machine noise, and other electrostatic discharge (ESD) events. TVS diodes represent a cost-effective way to address these events by providing a temporary blockage in electricity from the transient and in turn, shield the electronics.

The MXLSMCGLCE90A, for example, can be used in industrial and process control equipment, medical equipment, consumer electronics, telecommunications, automotive applications, and other markets where ESD immunity and voltage transient protection are desired.

Working Principle

TVS diodes protect against over-voltage transients by clamping the voltage at a certain level. They feature a zener breakdown region in between the cathode and anode, and are designed to exhibit both very low on-state conduction and very low off-state clamping voltage.

For example, the MXLSMCGLCE90A has a breakdown voltage of 26V ±15% and is able to handle a surge current up to 2.5A. This allows it to clamp the voltage at the preferred level and protect the device connected to it. As a result, it provides superior ESD, surge and over-voltage protection for sensitive electronic components.

Conclusion

In conclusion, TVS diodes, such as the MXLSMCGLCE90A, are designed to protect and limit the peak voltage of sensitive electronics from large voltage transients. They provide a cost-effective way to address these events and shield the connected device. TVS diodes are commonly used in a wide variety of applications, such as industrial and process control equipment, medical equipment, consumer electronics, telecommunications, automotive applications, and more.
