TVS（transient voltage suppressor）diodes or Transient voltage surge suppressors are clamping devices designed to protect electronic components from damage due to transient short duration overvoltage. The MXP6KE120A is a high performance TVS diode which designed for offer a high level of protection against electrical transients such as electrical noise, voltage spikes, and lighting transients.

MXP6KE120A Application Field

The MXP6KE120A can be used in a variety of applications especially those that require high power transient spike protection. This device was designed to protect diverse electronic products such as computers, cell phones, communications equipment, industrial control circuits, consumer electronics, motor drives and other sensitive electronic equipment.

This high performance TVS diode is also suitable in higher than normal ambient temperature or where a high power dissipation is needed. The MXP6KE120A is suitable for use in applications demanding an operating temperature range of -55° to 150°C.

MXP6KE120A Working Principle

The MXP6KE120A bi-directional protection device is based on avalanche breakdown principle. It offers superior reliability and excellent transient protection. The way it works is that when the voltage across the diode exceeds the maximum voltage (V_BR) by a certain amount, the device enters into an avalanche breakdown. The consequence is that it delivers a low impedance path, thereby diverting the excess current away from your sensitive circuits and possibly saving them from fatal damage.

The MXP6KE120A also comes with an ESD protection which is designed to shield the circuits from ESD pulses. This device offers ESD protection at ±40V and IEC 61000-4-2 level 4 compliance.

MXP6KE120A also offers current limiting protection. It detects excessive current and limits it to a safe level to protect your equipment from being damaged due to over current conditions.

Conclusion

In summary, the MXP6KE120A is a bi-directional high performance TVS diode which is designed to protect any sensitive electronics from transient voltage, electric noise, voltage spikes, and ESD. It is suitable to use in applications demanding an operating temperature range of -55° to 150°C and provides excellent reliability with excellent transient protection.
