Transient voltage suppression (TVS) diode is a specialized diode designed to protect sensitive electronic circuitry from damage caused by abrupt and excessive voltage transients, particularly those caused by electrostatic discharge (ESD).

The SM8S16AHE3-A/I is a robust and practical TVS diode that provides effective overvoltage protection for a wide variety of applications. It features low clamping voltage, low capacitance, and ultra-fast response times to protect anything from data lines to high performance ac-dc power devices.

The SM8S16AHE3-A/I is designed to prevent transient voltage from damaging sensitive devices by absorbing, storing and then dissipating high voltage spikes within a 15 nanoseconds response time. This device offers a low 5.5V to 10V reverse breakdown voltage, a very low 0.15pF capacitance, and a maximum peak pulse current of 8.3A and IEC 61000-4-2 compliant ESD protection.

The SM8S16AHE3-A/I is suitable for use in a wide range of applications, such as data lines, power lines, and ac-dc power devices. It also provides superior ESD, lightning, and other transient protection for any system where such protection is required.

In terms of working principle, the SM8S16AHE3-A/I protects circuits from transient voltage surges by using a several component circuit including a Zener diode, an avalanche diode, and a TVS diode. When the voltage across the diode exceeds the breakdown voltage, the avalanche diode will start to conduct. This in turn causes electrons to flow across the diode, storing energy near the junction and creating a voltage drop across the diode. The Zener diode serves to reset the circuit in the event of a false trigger, and the TVS diode further prevents excessive power spikes.

The SM8S16AHE3-A/I TVS diode is a practical solution for overvoltage protection applications, providing superior protection against transient voltage spikes and ESD. Its low-capacitance, fast response times, and robust design make it suitable for use in all kinds applications including data lines, power lines, and ac-dc power devices.
