Transient Voltage Suppressors (TVSs) are widely used in today\'s electronic devices to protect against electrical overstress. Among those, MA5KP100A is a unidirectional TVS diode specially designed to protect against voltage transients in low-voltage systems, like car electronics. This article will focus on the application field and working principle of MA5KP100A.

MA5KP100A is generally used as a bidirectional ESD protector in low-voltage systems, such as car electronics, which protect sensitive components from voltage transients and ESD strike. This TVS diode can efficiently work under a wide range of voltages and temperatures, from -30V to 28V and from -55℃ to 150℃ respectively. For this reason, MA5KP100A can be used to protect high-end car systems, like Electric Vehicle Lidar Detection Cables, as well as other sensitive industrial components.

The working principle of MA5KP100A is mainly based on its special structure. When a transient surge is applied to the TVS diode, the avalanche process occurs at the junction of the PN junction. As a result, holes and electrons are generated from the junction, and these charges will result in an increased current which is forced through the junction.

A stable voltage will establish in the junction after the transient surge is absorbed, and this will limit the power dissipation in the diode and thus the voltage across the diode. This will also help maintain the steady current in the diode, thus helping to protect the sensitive components connected to it.

Moreover, the strong housing of the diode also contributes to its performance. It has an extra-protection housing with an increased thickness and an electrostatic strength of at least 10,000V, which effectively protects the diode from outside interference. It also has a special four-piece ceramic base that helps to maintain the diode’s temperature stability.

In conclusion, MA5KP100A is a highly reliable protector to safeguard against voltage transients and ESD strike in low-voltage systems, like car electronics, EV lidar detection, and other electronic components. Its special construction and housing make it well suit for the arduous working conditions, and also its excellent performance in various temperature and voltage makes it the preferred choice of most industrial and automotive engineers.
