TVS ( Transient Voltage Suppression ) diodes are a key component in the protection of sensitive electronic components from the damaging effects of electrical over-voltage transients such as Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). In fact, TVS diodes are the most commonly used over-voltage suppressors in modern electronics. The MXL5KP17AE3 is a unidirectional over-voltage protection diode from Vishay TVS Semiconductor. It is part of the company’s family of unidirectional ESD protection devices that are designed to protect against ESD and EFT pulses.

MXL5KP17AE3 Application Fields and Working Principle

The MXL5KP17AE3 can be used for many applications such as protecting against excessive current energy, protecting low voltage signals, and providing protection against high voltage transients.

The MXL5KP17AE3 can provide protection up to 17 A peak pulse current with an 8/20 μs pulse waveform. It will work for breakdown voltages ranging from 5.6 V to 175 V, and has a maximum operating peak reverse voltage of 48.7 V. It has a reverse current of less than 1 μA at 135 V. It also features excellent clamping performance, and fast response time, making it an excellent choice for over-voltage protection.

When a voltage transient of an excessive magnitude is applied to an electronic component or system, the MXL5KP17AE3 will respond by clamping the voltage to a safe level. This is accomplished by the diode reducing the over-voltage to a safe level where no damage will be caused to the protected component or system. This is done by the diode absorbing the excess energy, converting it into heat which is then dissipated. This process is known as clamping action, and it is the main function of a TVS diode.

The MXL5KP17AE3 has excellent surge capabilities due to its robust construction. The diode is constructed from a substrate of silicon with aluminum nitride and silicon nitride added for protection against transient voltages and thermal shock. The diode also features extremely low leakage current, excellent thermal stability, and high ESD protection.

The MXL5KP17AE3 is an ideal choice for applications that require unidirectional protection from over-voltage transients. It is suitable for use in a variety of DC/DC converters and portable electronic devices such as smart phones, tablets, and laptops. It is also suitable for a wide range of applications, such as automotive, aerospace, military, and medical.
