TVS - Diodes
TVS (Transient Voltage Suppressors) diodes are designed for protection of electronics circuits from voltage surges, spikes and related destructive transients. MXLSMLG28CAE3 diodes are one of the many available devices in this category used for protection of both AC and DC generated circuitry.Application field and working principle
The MXLSMLG28CAE3 series diode is mainly used for various voltage transient protection applications, such as DVRs, TV receivers, power supplies, telecom systems and other electronic systems or equipment. It can also be used for protection against overvoltage and reverse voltage transients.Unlike traditional Zener diodes, TVS diodes are able to absorb significantly higher levels of energy due to their complex internal structure. Their key feature is a combination of a Diode and a Variable Resistor in one package. The internal structure of MXLSMLG28CAE3 diode can be divided into three parts; the Anode, the Cathode, and the Zener part. The Anode is the positive terminal, the Cathode is the negative terminal, and the Zener (also known as the Avalanche) part is the buried avalanche region between the Anode and the Cathode.When an external voltage higher than the rated breakdown voltage applied to the diode, the "Zener Part" is activated. The energy of the transient is absorbed by the Zener part and it is converted into heat energy and dissipated. This PV (Peak Voltage) clamping action reduces the voltage of the circuit to protect it from destruction or malfunctioning.Additionally, MXLSMLG28CAE3 diodes have a wide clamping voltage range and are capable of offering protection for both AC and DC circuits. In terms of performance, it offers high surge capability up to 140 amperes and low leakage current.In summary, the MXLSMLG28CAE3 series diode is an excellent choice for high voltage transient protection, thanks to its exemplary performance and wide clamping voltage range. Its combination of a Diode and a Variable Resistor in one package makes it a very versatile device for multiple surge protection applications.
