TVS-Diodes, otherwise known as transient voltage suppression diodes, are an essential line of defense against voltage surges from sources such as lightning strikes, load inductance, or power cycling. The MXSMBJ17AE3 TVS diode is a common example of surge protection devices on the market.

The MXSMBJ17AE3 is a leaded diode in a plastic package. The device has a stand-off voltage of 17V and a peak pulse power of 600W, with a nominal breakdown voltage of 26.8V. It also has a capacitance of 2.5pF and a remarkably low leakage current of 0.1mA at rated voltage.

The most common field of application of the MXSMBJ17AE3 is in automotive applications. It is used as an electronic component for surge protection and often installed on the circuit board of vehicles to safeguard their electronic components.

The working principle of the MXSMBJ17AE3 is based on an avalanche effect. This effect occurs when electrons and/or their corresponding ‘holes’ are accelerated in a semiconductor such as silicon. The electrons and ‘holes’ acquire sufficient momentum and energy to become free and travel across the material, creating an electrical current. When an electrical field is applied to the material, the electrons and ‘holes’ drift in the junction and the current flow increases exponentially until the diode breakdown voltage is reached.

The MXSMBJ17AE3 also features an ultra-fast response time, meaning it can react quickly to transient events and clamp them to protect the device. Once a transient event has dissipated, the device will automatically reset itself. The MXSMBJ17AE3 also offers low clamping voltage and high surge protection.

The MXSMBJ17AE3 can also be used in many other applications, such as television sets, DVD recorders, and other consumer electronics. With the use of this diode, such appliances can be safely operated in an environment with a high degree of electrical noise.

In summary, the MXSMBJ17AE3 is a transient voltage suppression diode that is mainly used in automotive applications. It is designed with a stand-off voltage of 17V and a peak pulse power of 600W. The diode features an avalanche effect that can protect against over voltage, and also has an ultra-fast response time with a low clamping voltage and high surge protection.
