MX1.5KE15AE3 Circuit Protection

Your current search has returned the MX1.5KE15AE3 TVS diode. TVS (transient voltage suppressor) diodes are a type of semiconductor device that offer protection against electrical overstress, such as lightning strikes or power surges. The MX1.5KE15AE3 TVS diode has certain characteristics that make it a very popular choice for use in various applications. In this article, we will discuss the application fields and working principles of the MX1.5KE15AE3.

Application fields

The MX1.5KE15AE3 has a breakdown voltage of 15V and stands out for its long surge life capability. It has a rated surge power of 550W and can handle a surge current of up to 1.5kA (8/20µs). These characteristics make this device ideal for use in low capacitance ESD protection applications.

The device can also be used in communication systems, audio and video equipment, LAN and telecoms applications, automotive ECU protection, monitoring systems and other similar systems for which low leakages and low clamping voltages are desired.

Working principle

The MX1.5KE15AE3 is a silicon avalanche diode, which means that it is designed to prevent conduction (the flow of electricity) by becoming resistive in the presence of an overload voltage. The diode switches on instantaneously when the voltage exceeds its breakdown voltage, and then begins to reduce the current flow to a safe level. This prevents the excess voltage from damaging the connected equipment.

The device also has ESD suppression capabilities. ESD (electrostatic discharge) occurs due to high voltages generated by friction between two objects, resulting in sparks or arcing. The MX1.5KE15AE3 can reduce the effects of an ESD event by absorbing the voltage and dispersing it across its junction.

Conclusion

The MX1.5KE15AE3 offers a high level of protection against electrical overstress events, such as lightning and power surges, as well as ESD. It is a popular choice for low capacitance ESD protection applications, and can also be used in communication systems, audio and video equipment, and automotive ECU protection.
