Transient voltage suppressors (TVS) are a type of semiconductor diode used to protect vulnerable devices from damage due to transient voltage spikes. In the case of the SMF11A-HE3-08, an 11A, 500V device with a symmetrical peak current and a low reverse leakage current, it can be used in a variety of applications.

One of the main applications of the SMF11A-HE3-08 is in protection against overvoltage. This means protecting sensitive electronics and wiring from voltage spikes caused by electrostatic discharge (ESD), lightning, or power faults. A key feature of the SMF11A-HE3-08 is that it has a low capacitance, making it suitable for high-speed circuit applications. It is also suitable for use in portable or mobile devices, as it has a wide operating temperature range.

Additionally, the SMF11A-HE3-08 can be used in applications such as automotive electronics, industrial equipment, and consumer electronics. In these applications, it can be used to help protect components from high voltage transients generated by high energy sources such as ignition coils, switching power supplies, electric motors, and more. It can provide protection against ESD, static discharge, lightning, and other problems.

The working principle of the SMF11A-HE3-08 is based on the principle of reverse bias breakdown. When a voltage greater than the rated peak surge current is applied to the device, the voltage break across the device increases significantly. This creates a reverse bias voltage across the device, allowing it to absorb the energy from the overvoltage surge. The result is that the voltage is limited and harmless energy is diverted away from the sensitive components or wiring.

In summary, the SMF11A-HE3-08 is a versatile device designed to protect much more vulnerable electronics from damage due to transient voltage spikes. It finds applications in a range of industries, including automotive, consumer, and industrial, and operates on the principle of reverse bias breakdown to absorb and divert the energy of an overvoltage surge away from sensitive components.
