TVS diodes are transil devices used to protect electronic circuits from overvoltage transients. The MSMLJ28CA/TR is a Unidirectional Electrostatic Discharge (ESD) protection diode designed to replace a wide range of discrete components and serve as protection of sensitive components from the destructive effects of ESD, when connected across the data transmission line.

The MSMLJ28CA/TR diode provides overvoltage protection for a wide variety of components and systems. Its low stand-off voltage of 28V, and maximum clamping voltage of 38V make it suitable for a wide range of applications in low voltage circuits. This includes protection for data lines, such as PATA, SATA and Ethernet interfaces.

The MSMLJ28CA/TR diode is packaged in a small, leadless SOD-523 Surface Mount Package, which provides an efficient, low-profile ESD protection solution. The SOD-523 package type is particularly attractive in high-density applications where a minimal PCB footprint is required. The diode is also RoHS compliant and enables easy design-in of high-density circuits by reducing the number of parts. It can be used in systems such as embedded devices, automotive applications, consumer electronics and industrial controls.

The MSMLJ28CA/TR diode operates on the avalanche breakdown principle, meaning it can absorb and dissipate up to ±30kV Electrostatic Discharge (ESD). This diode operates in ESD protection mode on the up-stroke of the transient voltage and begins reducing voltage on the down-stroke. This reduces component stress and ensures that any ESD events, such as generated when a person touches a system, are effectively eliminated.

The MSMLJ28CA/TR diode satisfies the IEC 61000-4-2 Level 4 standard, which requires protection for ESD events up to 30kV HBM. In addition, this diode is capable of in-circuit ESD testing to ensure that it complies with IEC 61000-4-2 Level 4 standard. This ensures the highest level of protection for sensitive components.

Overall, the MSMLJ28CA/TR diode provides excellent ESD protection in a wide range of applications due to its low stand-off voltage, low capacitance and surge current capability. The small SOD-523 package also allows for efficient, low-profile design in high-density applications. This diode meets the highest ESD protection standards, exceeding the requirements for IEC 61000-4-2 Level 4, providing reliable protection for sensitive components.
