Transient Voltage Suppressors (TVS) play an essential role in protecting sensitive electronics from transient overvoltage due to inductive loads, electrostatic discharge (ESD), lightning, and other electrical transients. The SM8S15AHE3/2D is a TVS diode designed for such applications. This article will discuss the application field and working principle of this particular device.

The SM8S15AHE3/2D has a working voltage of 15V and a working power of 2 Watt, making it suitable for medium-power electronics such as computers, telecom systems, and consumer electronics. It features dual-channel operation, which helps to protect against transient overvoltages on both Suppressors, and its extreme fast response time helps to protect against damaging ESD.

The SM8S15AHE3/2D is designed to protect against transients of up to 8 kV. This makes it suitable for a wide range of industrial, automotive, and medical applications. It is also suitable for industrial electronic control systems, including PLCs, industrial controllers, inverters, and high power motor controllers.

The working principle of the SM8S15AHE3/2D is to remain open until a voltage above its clamping voltage is present. When this voltage is reached, it acts as a low impedance between the source and the load, clamping the voltage and dissipating the energy as heat. This helps to protect sensitive electronics from overvoltage and dissipate any transients that may be present.

The SM8S15AHE3/2D is also designed to contain the impact of lightning strikes, helping to prevent the spread of damaging transients. Its breakdown reversing voltage is 140V, so it can handle transients up to this level before triggering the device. This makes it suitable for applications such as automotive and industrial wiring, as well as many consumer electronics.

Overall, the SM8S15AHE3/2D is a versatile and reliable TVS diode that can be used in a wide range of applications. Its fast response time and high-voltage threshold make it suitable for high-power electronics, while its dual-channel operation helps to protect against transient overvoltages on both Suppressors. It is also designed to contain the impact of lightning strikes, helping to protect sensitive electronics from the damaging effects of electrical transients.
