TVS - Diodes

TVS-Diodes, also known as transient voltage suppression (TVS) diodes, are a type of semiconductor device used for protecting electrical circuits from high-voltage transients, pulses, and noise. They are commonly used to protect vulnerable electronic components from the damaging effects of voltage spikes caused by Electrostatic Discharge (ESD), Lightning, and Switching Transients.

SMBG9.0A-E3/5B is a type of TVS-Diode specially designed for over-voltage protection in 10/200V AC lines. It is a surface mount device with a high dielectric strength of 1500V rms and has a breakdown voltage of 3.14KV at 100A, making it ideal for industrial and military applications. In addition, the SMBG9.0A-E3/5B features a low clamping voltage of 78 volts at 1K Amp, ensuring reliable protection of sensitive components from high voltage transients.

The working principle of the SMBG9.0A-E3/5B is based on the p-n junction of the semiconductor material used in the diode. The diode consists of two metallic contacts, one connected to the anode and the other connected to the cathode. When a reverse electrical field is applied to the junction of the two contacts, electrons start flowing from the anode to the cathode and an avalanche breakdown is initiated. This breakdown will clamp the voltage at the junction, protecting the electrical circuit from further damage due to high voltage transients.

Due to its robust design and high breakdown voltage, the SMBG9.0A-E3/5B is suitable for high voltage applications such as AC line filters, surge protectors, and motor control systems. Additionally, the low clamping voltage of 78V at 1K Amp ensures that sensitive components are protected from high voltage transients. This makes the SMBG9.0A-E3/5B an ideal choice for applications requiring reliable and robust protection from surges.

In terms of applications, the SMBG9.0A-E3/5B can be used in a variety of industrial and military applications, such as AC line filters, surge protectors, motor control systems, power factor correction (PFC) systems, inverters, and battery management systems. Furthermore, the SMBG9.0A-E3/5B can also be used in consumer electronic products such as mobile phones, laptops, and LCD TVs.

Overall, the SMBG9.0A-E3/5B is an ideal choice for over-voltage protection in 10/200V AC lines due to its robust design and high breakdown voltage. Its low clamping voltage provides reliable protection of sensitive components from high voltage transients, making it suitable for a variety of industrial and military applications. Furthermore, its small size and ease of installation make it well-suited for consumer electronic products.
