A TVS diode, or transient voltage suppressor, is a specialized electronic component designed to protect sensitive components and equipment from electrical overstress (EOS). The MXL1.5KE18A is a unidirectional Transient Voltage Suppressor (TVS) designed as an IEC61000-4-2 ESD protection device. This diode has an excellent clamping capability and very fast response time, which is ideal for applications requiring a robust, reliable and fast ESD protection circuit.

The MXL1.5KE18A is a surface mount silicon avalanche diode housed in a blue lead-free SOT-23 package. It is designed to protect against high-energy transients from ESD and other electrical overstress events up to 25 kV. This diode has a working peak pulse power of 1500 W and a breakdown voltage of 18 V, with an IEC61000-4-2 Level 4 capability. The device is RoHS compliant, halogen free and has a maximum capacitance of 15pF.

The primary application of the MXL1.5KE18A is ESD protection in consumer electronics. It can be used in any device that is exposed to voltage spikes or high-energy transients, such as smartphones, tablets and computers. This diode is also ideal for automotive applications, as its robust design is suited for durability and long lifetime expectancy.

The MXL1.5KE18A works by quickly responding to voltage spikes and diverting the current away from the protected circuit. This diode acts as a voltage-limiting protection device and is triggered by voltage levels above the breakdown voltage of 18 V. When a voltage surge occurs, the diode will start to conduct the current, diverting it away from the protected components. This behavior limits the maximum voltage that can be applied to the protected circuit.

The fast response time and high peak power capability of the MXL1.5KE18A make it ideal for automotive applications. It has an extremely low clamping voltage due to its low forward voltage drop, and its robust design makes it suitable for use in harsh environments. Additionally, the small form factor of this diode allows it to be more easily integrated into devices where space is limited.

The MXL1.5KE18A is a reliable and robust unidirectional transient voltage suppressor designed for ESD protection in consumer electronics and automotive applications. It offers a fast response time and a high peak power rating of 1500 W, making it an ideal choice for devices that are exposed to high-energy transients. Thanks to its low clamping voltage and small form factor, this diode is easy to integrate into any circuit.
