TVS diodes provide an effective protection mechanism for electronic systems when transients such as electrostatic discharge or voltage spikes occurs. The MXSMBJ10AE3 is a bi-directional TransilTM Transient Voltage Suppressor (TVS) device designed to protect sensitive equipment against electrostatic discharge (ESD) and lightning related transient events. Its low capacitance and low clamping ratio makes it ideal for data- and signal-lines. The device suppresses transients with clamping and peak power ratings of 10A (tp= 8/20µs ) and 400W.

Application Field

The MXSMBJ10AE3 is suitable for applications requiring protection from ESD, CDE, lightning transients, power induction, capacitor discharge, and other transients. Typical applications include telecom, military, and consumer equipment. The device is designed to protect sensitive components such as digital-line driver circuits, high voltage batteries, high-speed logic circuits, and other similar devices against transients.

Working Principle

The MXSMBJ10AE3 device works by absorbing any high-voltage pulses or spikes that occur above a certain voltage threshold (Vt). When a transient event occurs, the device\'s avalanche junction turns on, creating a low-resistance conductive path that shunts the voltage spike to ground. The device continues to be conducting until the voltage transient event below the cutoff voltage (Vcl), at which point, the device turns off. The device is bi-directional, meaning that it has the ability to protect from both over-voltage transients and under-voltage transients.

The MXSMBJ10AE3 device also uses its internal capacitance to provide ESD protection. When an ESD event occurs, the device\'s internal capacitance allows the device to absorb the voltage spike without damaging the protected components. Additionally, the device\'s low capacitance ensures that it does not interfere with the data signal.

Conclusion

The MXSMBJ10AE3 is a bi-directional TransilTM Transient Voltage Suppressor (TVS) device designed for applications requiring protection from ESD, CDE, lightning transients, power induction, capacitor discharge, and other transients. Its low capacitance and low clamping ratio makes it ideal for data- and signal-lines. The device works by absorbing any high-voltage pulses or spikes that occur above the cutoff voltage, and its internal capacitance allows the device to absorb the voltage spike without damaging the protected components. Thus, the MXSMBJ10AE3 is ideal for protecting sensitive electronic systems and components from damaging transient events.
