5KP45HE3/54

TVS - Diodes

TVS diodes are an essential protection component for preventing overvoltage, overcurrent, and electrostatic discharge. 5KP45HE3/54 is a 5.0-Watt DO-214AC bidirectional surface-mount Transient Voltage Suppressor (TVS) diode with a typical 5.0-W breakdown rating and a 5.0 A hold current. Its quick response and robust construction make it the ideal choice for applications requiring lightning or ESD protection.

Application Field and Working Principle

A 5KP45HE3/54 diode is a highly reliable, unidirectional or bidirectional, double-diffused, reverse-breakdown device. It is designed to provide protection against external disturbances such as electrical transients, lightning, electrostatic discharges, and other forms of overvoltage. As it absorbs transients, it dissipates the excess energy in a controlled manner, thus safeguarding the connected components. It is an indispensable device in most of the switching power supply applications such as AC/DC, DC/DC conversion, I/O protection and speed/power control circuits.

The 5KP45HE3/54 is a diode designed for transient voltage suppression, and has a working principle similar to that of a standard rectifier diode. It consists of a p-n junction that is normally reverse biased. A surge or pulse of energy is absorbed by the diode, and then dissipated as heat. When the surge reaches the breakdown voltage levels (the diode\'s avalanche breakdown), it allows the current to flow and then quickly resumes its normal state after the surge is gone. This process helps to protect the connected components in the circuit from damaging voltages.

When it comes to 5KP45HE3/54\'s application field, it is widely used in Automotive electronics, Communication devices, Consumer electronics, Industrial and Enterprise electronics, Telecommunications networks, as well as other areas that require a reliable means of protecting sensitive components from overvoltage or electrostatic discharge.

5KP45HE3/54 is the perfect choice for low-cost applications which need both a robust construction and a fast response. Its low forward voltage prevents self-heating, and its excellent clamping capabilities makes it the ideal choice for a wide variety of overvoltage protection needs.

In short, 5KP45HE3/54 provides dependable protection against voltage and current transients as well as electrostatic discharge both in the industrial and consumer sectors. It is a cost-effective device that is both robust and offers a fast response.
