TVS (Transient Voltage Suppression) diodes, specifically 5KP90HE3/73, are widely used in electronic applications for their high tolerance to voltage transients. The 5KP90HE3/73 is a standard type of TVS diode, with a rated maximum surge current of 9A and a peak pulse power dissipation of 90W. It is used extensively in a variety of applications, such as automotive, computing, telecom, consumer electronics, and industrial equipment.

The basic working principle of a 5KP90HE3/73 diode is relatively simple. It is a solid state semiconductor device that utilizes the effects of high electric fields on the material structure to achieve its protective function. The diode is designed in such a way that it acts as a one-way resistor. This means that any voltage beyond its specified maximum rating will be blocked and diverted to ground. Thus, any transient spikes or surges in the voltage that exceed the diode’s rating will be safely absorbed and dissipated.

A 5KP90HE3/73 diode is mainly used in automotive applications. It is designed to protect certain parts of the circuit from electrical transients induced by the engine, such as spark plugs or ignition coils. This type of diode is especially important in modern automotive designs, as they are much more susceptible to transients due to the use of complex electronic control units. The diode also offers protection in other contexts, such as in the telecom and consumer electronics industries, where it is used to protect sensitive components from power surges.

Apart from automotive applications, 5KP90HE3/73 diodes are widely used in computing applications. It is primarily used in the power supply unit of a computer to protect sensitive components from electrical spikes. The diode is also employed for ESD (electrostatic discharge) protection in a variety of small devices, such as cell phone chargers and portable electronic devices.

The 5KP90HE3/73 is also versatile enough to be used in industrial applications. It is most commonly employed to protect the input power supply of industrial machinery and automated systems from electrical spikes. This type of diode is ideal for industrial applications, as they are designed to handle large electrical transients. They are also highly reliable, offering robust protection for sensitive machinery.

Overall, the 5KP90HE3/73, like all TVS diodes, is an invaluable component in a wide range of applications, from automotive to industrial to consumer electronics. Its ability to absorb and safely dissipate electric transients makes it a reliable and effective protective device. Additionally, its small physical size makes it ideal for applications where space is at a premium.
