TVS diodes, also known as Transient Voltage Suppressors (TVSs), are a form of general purpose diode which helps to prevent damage caused by transients in electrical circuitry. The 5KP18A-E3/73 is one of the most commonly used TVS diodes for AEC-Q101 qualified applications.

The 5KP18A-E3/73 is rated for an operating current of 9.0A and a peak current of 18A. It has low capacitance and high frequency performance so that it can be used effectively in high-speed and high-frequency switching applications. It also has a working voltage of 33V and a high peak pulse power rating of 18kW, making it suitable for high power applications.

The 5KP18A-E3/73 can be used in a variety of applications, such as automotive, telecommunications, computer, and other electronics equipment. It has a low operating temperature of -55°C to 125°C and is rated for an insulation voltage of 870V.

The working principle of the 5KP18A-E3/73 is based on its use as a shunt element in an electrical circuit. This allows the protection diode to reduce the flow of current during transients, thus preventing damage from occurring to the protected electronic components. The 5KP18A-E3/73 is designed to be used in series with other components to provide surge suppression, so that the protected components remain intact in the event of an unexpected surge of voltage or current.

The 5KP18A-E3/73 is also equipped with an internal thermal shutdown feature that prevents it from overheating during peak current events. It is designed to provide protection from high current and high energy transients, which can damage or destroy unprotected electronic components.

In summary, the 5KP18A-E3/73 is a robust and reliable TVS diode designed for use in a wide range of AEC-Q101 qualified applications. It has a wide operating temperature range, high peak power rating, low capacitance, and an internal thermal shutdown feature. This makes it suitable for use in high-power and high-frequency applications, such as the automotive, telecommunications, computer, and other electronic equipment markets.
