TVS - Diodes, also known as transient voltage suppression diodes, are semiconductor devices used mainly for protecting electrical circuits from damage caused by overvoltage transients. They are primarily used for controlling, coordinating, and managing the voltage and current generated by electrical devices. In this article, we will take a look at the application and working principle of the MXLSMLG28CA TVS - Diode.

MXLSMLG28CA is a 5.0V unidirectional TVS with low capacitance and high surge current capabilities. It is a low capacitance device designed to protect sensitive electrical and communication systems from voltage transients generated by lightning, electric motors, wring shorts, switchmode power supplies, and industrial noise. It has excellent clamping capability at the rated Standoff avalanche and Peak Pulse Power, allowing it to act as both a standalone overvoltage protector and as a safeguard when bonded in series with other devices.

The MXLSMLG28CA TVS diode has an operating voltage of 5.0V, a Standoff voltage of 4.0V, and a Peak Pulse Power of 600W. It has low capacitance of 0.5pF and is housed in a 2-pin SOT-23 SMT package. This makes it ideal for applications where space is a premium, and where high Clamping Voltage and Low Leakage Current are important requirements. The MXLSMLG28CA is RoHS compliant and is made from a low-voltage Si material.

The working principle of the MXLSMLG28CA TVS diode is fairly straightforward. It is designed such that when the surge voltage exceeds the breakdown voltage Rating, a low resistance Path is formed. This creates an increase in the forward Current, which in turn causes a voltage drop across the diode. This means that the voltage supplied to the load is reduced significantly, thus limiting the amount of electrical damage caused.

This phenomenon is known as the “avalanche breakdown” which is the main reason why TVS diodes are used in voltage Transient protection. Furthermore, the low capacitance of the device, combined with its efficient energy absorption properties further increases the level of protection provided.

The MXLSMLG28CA TVS diode has a wide range of applications due to its features. It is an ideal choice for equipment that require high frequency, high voltage protection, such as: LED lighting, communication equipment, telecoms, automotive, computer peripherals, and consumer electronic devices. It is also suitable for applications in which low capacitance and low clamping voltage are required, such as servers, consumer electronics, test and measurement equipment, and any other device that requires transient voltage protection.

In conclusion, the MXLSMLG28CA TVS diode is an excellent choice for transient voltage protection. It has a low capacitance, a high surge current rating, and a high Peak Pulse Power. Furthermore, its low clamping voltage makes it a great choice for applications where space is at a premium. All in all, this TVS diode is an excellent choice for a variety of applications.
