TVS (transient voltage suppressor) diodes are unidirectional devices used to protect sensitive electrical and electronic components from the damaging effects of electrostatic discharges. The type of device used for such protection depends on the application requirement and the environment in which it will operate. A good example of a type of TVS device used in a variety of applications is the SMAJ120A M2G. This article will discuss the application field and working principle of the SMAJ120A M2G, how it is used, and the benefits it provides.

The SMAJ120A M2G is a general purpose, unidirectional, three-terminal, silicon avalanche TVS diode designed to protect sensitive electronics from transient over-voltage events such as electrostatic discharge (ESD) and lightning strikes. It is capable of protecting low voltage systems up to 28 volts, and its low capacitance makes it ideal for protection during RF transmissions. The SMAJ120A M2G provides a tight clamping voltage under surge conditions, and its bidirectional capability makes it an excellent choice for reverse polarity protection. It is also RoHS compliant, making it an ideal choice for applications requiring high levels of environmental protection.

In terms of application fields, the SMAJ120A M2G is a suitable solution for protecting automotive electronics from ESD, providing transient protection for sensitive data lines, protecting industrial control systems and equipment from power surges, protecting telecom equipment from lightning, and providing reverse polarity protection on low voltage power systems. The device’s low capacitance and bidirectional protection make it an ideal choice for mobile communication applications, where it can protect sensitive electronics from ESD and provide reverse polarity and lightning protection.

The working principle of the SMAJ120A M2G is based on a combination of avalanche breakdown and the zener effect. It is a device that is normally in the off state, which means that no current can flow through the diode until a voltage higher than the breakdown voltage is applied. When this occurs, the diode enters the avalanche breakdown mode. This mode channels the current, resulting in the device\'s ultra-fast response time of less than 0.5 nano-seconds. Additionally, the device also uses the zener effect to absorb the surge current and clamp the voltage. The zener voltage is determined by the device\'s ability to dissipate energy, with an exact value dependent on the specific part.

The SMAJ120A M2G is an ideal solution for many applications, and its bidirectional capability and low capacitance make it well suited for a wide variety of applications. It provides effective protection against ESD, lightning, and reverse polarity, making it a reliable and cost effective solution. In addition, its RoHS compliance makes it an ideal choice for applications requiring high levels of environmental protection.
