TVS diodes have the unique ability to protect sensitive electronic equipment and components from dangerous overvoltage surges. This protection is achieved through the use of Semiconductor devices known as Transient Voltage Suppressors (TVS). The MASMCJ28AE3 is a unidirectional / bilateral Ultra low capacitance single line Transient Voltage Suppressor (TVS) that is designed to protect data lines from Electrostatic Discharge (ESD), electrical fast transients (EFT), and lightning induced surges. This device is available in a roll bondable SMC package which offer uniform clamping action across the common mode range.

Working Principle of the MASMCJ28AE3

At a high level, the working principle of the MASMCJ28AE3 is based on the principle of avalanche breakdown. In this breakdown effect, when a high electric field is built up in the semiconductor junction, as it exceeds the BE junction breakdown voltage, the current in the junction increase sharply. This breakdown effect is known as avalanche breakdown. The breakdown voltage for the MASMCJ28AE3 is 28 Volts.

The device utilizes Silicon Avalanche Capable technology to achieve ultra low capacitance performance in a single line protection application. The device is designed to provide superior suppression of ESD, EFT, and lightning induced transient surge events. The MASMCJ28AE3 is designed to have a low capacitance performance of less than 1.5pF for ESD voltage up to ± 30KV.

Application Field of the MASMCJ28AE3

Due to its superior capacitance performance and low clamping voltage, the MASMCJ28AE3 is ideal for protecting communications systems, batteries, and other analog and digital devices from over-voltage surge. The device offers an excellent ESD protection for analog and digital systems. It is particularly useful for protecting high-speed communication lines from ESD and EFT pulses. The device is also perfect for protecting laptops, tablets, and consumer electronics from EFT and ESD. Additionally, it can also be used to protect sensitive components from lightning induced surges.

The device is RoHS compliant and Halogen free, which makes it compliant to European environmental regulations. The device is also integrated with electrostatic discharge (ESD) protection diode, which provides improved suppression and improved response performance. The device’s superior capacitance performance and low clamping voltage, make it the perfect choice for protecting electronic systems from over-voltage overwhelm.
