TVS (Transient Voltage Suppressors) are a form of protection for circuits in high- and low-voltage applications. TVS diodes are widely used in a variety of applications including protection from lightning, power supply etc. The 5KP85AHE3/54 is a unidirectional TVS with a maximum standoff voltage of 5.5V that can protect circuits from high transients.

The 5KP85AHE3/54 consists of three parts; a diode, a zener diode and a transistor. The diode is used to provide protection against transients from high-voltage power lines. The zener diode provides an adjustable voltage protection reference to prevent over-voltage. The transistor is used to control the current through the diode.

In operation, the 5KP85AHE3/54 is designed to detect and limit the voltage levels of high- and low-voltage transients. When a transient voltage exceeds the diode’s breakdown voltage, the device will conduct, thus limiting the voltage level before it reaches the protected circuit. The zener diode also provides a reference voltage to ensure the voltage level does not exceed the rated breakdown voltage. The transistor controls the current through the diode preventing the current from exceeding the device’s maximum rating.

The 5KP85AHE3/54 TVS is widely used in high- and low-voltage applications such as power supplies, data transmission, and video cameras. It is also used to protect USB cables from electrostatic discharge (ESD) and electromagnetic interference (EMI). It is designed to offer fast over-voltage protection and is capable of providing up to 10A peak pulse current.

The 5KP85AHE3/54 TVS is a widely used device for protection from high- and low-voltage transients. It consists of a diode, a zener diode, and a transistor to provide an adjustable voltage protection reference. Its fast-acting nature and the capability of providing up to 10A peak pulse current make it suitable for a wide range of high- and low-voltage applications such as power supplies, data transmissions, and video cameras. By limiting the voltage levels of transients before they can reach the protected circuit, the 5KP85AHE3/54 TVS can protect circuits from over-voltage.
