The MXL1.5KE56A is a unidirectional high surge current TVS(transient voltage suppressor) diode. This device provides discrete component solutions for protecting sensitive component and circuitry from dangerous voltage transient events such as electrostatic discharge(ESD), lightning induced surges, and AC mains instabilities. It comes with an easy-to-use Cathode and Anode marking for polarity. Its glass-passivated junction ensures its long-term reliability. In addition, its fast response time ensures a great level of circuit protection against ESD, lightning surges, and AC mains instabilities.

Applications of the MXL1.5KE56A

The MXL1.5KE56A is designed for the protection of delicate electronics from damages caused by transient voltage surges. Common applications of this TVS diode include protection of automotive sensors, electronic devices, wireless communication, and consumer electronic equipment. Besides, it can be used to secure various I/O ports including HDMI, USB, and Ethernet ports. The MXL1.5KE56A is also suitable for the protection of industrial applications such as controllers, motors, and other sensitive electronic components.

Working Principle of the MXL1.5KE56A

The MXL1.5KE56A have a lightning surge capability up to 10A@ 8/20 μs surge current and a stand-off voltage of 56V. This means it is capable of clamping transient voltage surges of up to 72V. During normal conditions, the diode will be in its low-resistance forward-biased state. In the event of a voltage transient, the diode’s p-n junction is disrupted, creating an avalanche state. The high current flow generated by this state ensures that the voltage transient is clamped. As the voltage transient passes and the diode returns to its forward biased state, the device resumes its intended operation.

Conclusion

The MXL1.5KE56A is a TVS diode designed to protect sensitive electronic components from voltage transients such as ESD, surges, and AC mains instabilities. It offers fast response and no follow current, with an Ipp (8/20 μs) of 10A and a stand-off voltage of 56V. It can be used in the protection of automotive sensors, consumer electronic equipment, wireless communication, industrial motors, and other delicate electronics. The MXL1.5KE56A is a versatile device designed to provide efficient protection in many different areas.
