TVS - Diodes: MSMLJ75A application field and working principle

TVS (Transient Voltage Suppressor) diodes are one of the most popular semiconductor components used for high voltage protection. From mobile phones to uninterruptible power supply (UPS) systems, these devices protect many electrical and electronic systems from electrostatic discharge (ESD) and lightning strikes. In this article, the application field and the working principle of a specific type of TVS diode will be discussed; the MSMLJ75A. The MSMLJ75A is designed to protect sensitive AC & DC equipment from voltage transients and surges. It is available in 8-pin, 4-lead leaded packages with maximum leakage current of 400nA and maximum capacitance of 2pF. It has a stand-off voltage of 75V, a clamping voltage of 88V (at a peak pulse current of 8.3A) and it is capable of handling transients up to 9.1kV (8/20 μs pulse). The MSMLJ75A is used for a variety of different applications. In ESD protection, it is used in products such as portable devices, consumer electronics and telecommunication equipment. In high-speed data lines, it is used for mitigation of unwanted signal reflections. In automotive electronics, it is used to protect against transient events such as switching loads on vehicles and induction loops. In medical devices, it is used to protect against indirect patient contact with high voltage transients. It is also used in intelligentized buildings, industrial automation, vending machines, and many other applications.The working principle of the MSMLJ75A TVS diode is quite simple. It operates by clamping excessive voltages that occur due to transient events, such as ESD or lightning strikes, to a safer level. This is achieved by the semiconductor material inside the TVS diode, which is formed into a ‘U’ or a ‘V’ shape with a small gap in between them. When an over-voltage occurs, the diode is triggered and the gap between the two semiconductor regions is filled by electrons, allowing a certain amount of current to flow. This limits the rise in voltage and ensures that the system is not damaged. Furthermore, the MSMLJ75A is fixed with a positive temperature coefficient (PTC) thermistor. It is designed to protect sensitive circuits and devices by absorbing large potential extreme transient surges above the stand-off voltage. In summary, the MSMLJ75A TVS diode is a highly reliable and cost-effective solution for ESD, lightning strike and other transient voltage protection needs.
