TVS (Transient Voltage Suppressors) diodes are a class of semiconductor devices designed to protect electrical and electronic equipment from transient (high surge) voltages in the range of 5V to 400V. They work by clamping the voltage to a level below the peak voltage of the surge, thereby preventing damage caused by the surge. The SMBJ100ATR is a popular TVS diode with a breakdown voltage rating of 100V and a peak pulse power rating of 600W. It can be used to protect a wide range of circuits and is particularly suited to telecommunications, automotive, and industrial applications.

The SMBJ100ATR is essentially two interconnected Zener diodes. Zener diodes are used for voltage regulation by allowing current to flow in only one direction when the voltage reaches a specific level. In the case of the SMBJ100ATR, when the voltage exceeds 100 volts, current will start to flow through both of the Zener diodes, effectively creating a low resistance path and clamping the voltage to 100 volts. This prevents the voltage from exceeding this level and thus, protects the component from the surge.

The SMBJ100ATR can be used in a variety of applications. It can be used to protect components in power supplies, automotive electronics, communications, and industrial controls. It is particularly useful in protecting sensitive microprocessors, which are vulnerable to power surges. In telecommunications, it can be used to protect phone lines and data lines from transient spikes. In automotive applications, it can be used to protect sensors and ECUs from high voltage transients induced by load dumps and ESD.

The SMBJ100ATR is designed for high surge protection and is rated for a higher peak pulse power than some other TVS diodes. It is also available in a surface mount package and has a low clamping voltage, making it suitable for high speed data applications. It is manufactured to strict specifications, ensuring excellent reliability in a wide range of operating conditions.

In conclusion, the SMBJ100ATR is a popular TVS diode with a breakdown voltage of 100V and a peak pulse power rating of 600W. It is suitable for a wide range of applications, particularly telecommunications, automotive, and industrial applications, and is designed for excellent reliability and surge protection. It is available in a surface mount package and has a low clamping voltage, making it suitable for high speed data applications.
