Transient voltage suppression (TVS) diodes are special kind of diodes that are used to limit the voltage applied to electronic circuits by absorbing transient voltages. The MXSMBJ16AE3 is a low capacitance, unidirectional, PPAC 12V transient voltage suppressor from EIC discrete semiconductors. In this article, we will discuss the application fields and working principle of this TVS diode.

Application Field

The MXSMBJ16AE3 is a TVS diode designed for the protection of sensitive electronics equipment from transients caused by lightning, electrostatic discharge (ESD) and other electrical over-stress events. It is specifically designed for applications such as automotive electronics, industrial electronics, telecommunications, set-top boxes, and home appliance control panels. The MXSMBJ16AE3 has a clamping voltage of 26.6V and an operating temperature range from -55°C to +150°C, making it suitable for a variety of applications.

The MXSMBJ16AE3 is a low capacitance TVS diode with a maximum capacitance of 2.5pF and a typical capacitance of 1.5pF. This makes it ideal for suppressing transients on high speed circuits and for RF applications. Due to its low capacitance it also has low filtering and signal integrity performance. Another feature of the MXSMBJ16AE3 is its low leakage current of 1uA which provides added protection against over-voltage conditions. Finally, the MXSMBJ16AE3 is RoHS compliant, making it suitable for a variety of applications requiring lead-free components.

Working Principle

TVS diodes operate by limiting the voltage applied to a circuit through the use of a Zener diode. When a voltage above the breakdown voltage of the Zener diode is applied, the diode conducts, allowing current to flow through the diode and limiting the voltage across the diode. This reduces the voltage at the output of the circuit and prevents damage to the circuit components.

The MXSMBJ16AE3 works by limiting the voltage applied to the circuit to 26.6V. When the voltage exceeds this value, the diode will conduct and allow current to flow, limiting the voltage at the output of the circuit. The Zener diode also provides a low capacitance of 2.5pF, allowing it to be used for high speed and RF circuits. The low leakage current of 1uA ensures that the diode is not affected by over-voltage conditions.

In summary, the MXSMBJ16AE3 is a low capacitance, unidirectional, PPAC 12V transient voltage suppressor from EIC discrete semiconductors. It has a clamping voltage of 26.6V and is suitable for a wide range of applications including automotive electronics, industrial electronics, telecommunications, set-top boxes, and home appliance control panels. The low leakage current of 1uA and low capacitance of 2.5pF make it suitable for high speed and RF applications. Finally, it is RoHS compliant, making it suitable for lead-free applications.
