Introduction:

The MXLSMLJ28A is a Thyristor Surge Suppressor (TVS) device used to protect sensitive electronic equipment from transient voltages. Known as a single-diode TVS (SdTVS), it is part of a larger family of transient protection ICs called Transient Voltage Suppressors (TVSs).

Application Field:

The MXLSMLJ28A is suitable for use in a variety of industrial and consumer electronic applications, however the primary application field for this device is touch-screen displays. This type of application is particularly demanding in terms of transient protection due to their touch-screen technology and sensitive sensor array connections.

The MXLSMLJ28A is also suitable for use in audio applications such as musical instruments and gaming devices. A specialized version of the capacitor cluster is available for this type of application which features a very low leakage and excellent pulse wave distortion characteristics.

Working Principle:

The MXLSMLJ28A utilises an avalanche-clamping mechanism which is activated during a transient. This allows the device to absorb the energy of the transient in a very short time span and clamp the voltage to a safe level. It also provides excellent EMI suppression, making it suitable for sensitive electronic applications.

The device also features a capacitor cluster which provides additional protection against fast transients. This cluster can be customized to tailor the device’s performance and offer protection from different types of transients.

Conclusion:

The MXLSMLJ28A is a versatile and reliable single diode TVS solution that is suitable for use in a variety of industrial and consumer applications. Its ability to provide excellent EMI suppression and fast over-voltage protection makes it an ideal choice for a wide range of applications that demand a high level of transient protection.
