SM6S15AHE3/2D Application Field and Working Principle of TVS - Diodes

TVS - Diodes have become increasingly popular in modern electronic devices as protective elements on signal and power traces to guard against voltage surges. SM6S15AHE3/2D is one of the commonly used TVS - Diodes. It is designed to protect signal and power traces against unwanted transient voltage spikes. In this article, an overview of the application field and the working principle of SM6S15AHE3/2D TVS - Diodes are introduced.

Application Field

SM6S15AHE3/2D is a widely used surface-mount diode. Its applications include such as mobile phone systems, PCs/laptops, LCD TVs, car audio systems, consumer electronics and more. The device\'s small surface-mount package size makes it practical for use in these types of applications. It provides ESD protection on sensitive signal/power paths, and is suitable for protecting single lines from transient spikes or pulse waves.

Working Principle

A SM6S15AHE3/2D TVS - Diode is a three-terminal device that acts as a voltage clamp. It has a low forward voltage drop (typically 0.3 V) and a high reverse breakdown voltage (≥24 V). When an external transient voltage is applied, the diode\'s PN junction immediately begins to conduct, causing a voltage drop across the diode. The maximum current sustained by the diode is determined by its power rating. When the voltage across the diode exceeds the breakdown voltage, the diode\'s avalanche characteristics cause the current to rise rapidly. This limits the peak current and clamping voltage acting on the system. The device can handle repetitive transient voltage spikes, up to its power dissipation rating. When the transient voltage passes, the diode\'s junction immediately returns to its blocking mode.

In summary, SM6S15AHE3/2D is a commonly used TVS - Diode for protecting signal and power traces against unwanted transient voltage spikes. It has a low forward voltage drop and high breakdown voltage. It is suitable for protecting single lines from transient surges, and can handle repetitive spikes up to its power ratings.
