5KP8.0A-E3/73

TVS - Diodes Application Field and Working Principle

The 5KP8.0A-E3/73 is a silicon-avalanche TVS (transient voltage suppressor) diode designed to protect electronic equipment from destructive transient overvoltages that can easily damage sensitive electronic components. These transients can be caused by lightning, electrostatic discharge and inductive surges. TVS diodes are commonly found in electronics such as computers, smart phones, digital cameras and other consumer and commercial electronics.

TVS diodes are basically unidirectional protection devices that clamp the transient voltage across its terminals. They are usually packaged as surface mount devices, and their primary function is to quickly clamp and divert the excess voltage or current away from the load in order to protect it. The 5KP8.0A-E3/73 is a bi-directional device that can protect against transient voltages in either direction. This makes it suitable for a wide range of applications from consumer electronics to more robust industrial control systems.

When a transient voltage is applied to the 5KP8.0A-E3/73 TVS diode, it rapidly discharges the excess voltage or current which prevents it from reaching the load. This is achieved by a highly sensitive and fast trigger of the avalanche breakdown mechanism. It is triggered by a buildup of electric field at the anode region of the diode, due to the voltage or current applied. As a result, a large number of charge carriers are generated due to the simplified band structure in the anode together which results in a sharp increase in the current. This creates a avalanche current which quickly clamps and diverts the superfluous voltage and current away from the load.

The 5KP8.0A-E3/73 offers a wide range of advantages and features including low leakage current, rated power rating of 8 Watts, fast response time of less than 1 nanosecond and a wide operating temperature range of -55°C to +125°C. It has a wide dynamic range of transient voltage suppression from 5K to 8K Volts and it can handle at least 8.0 Amps of surge current. The device is also RoHS compliant.

Overall the 5KP8.0A-E3/73 TVS Diode is an excellent protection solution for a variety of electronic applications, offering both reliable performance and economical pricing. It is easy to install and maintain, and offers high immunity to noise and transients generated either by lightning, electrostatic discharge or inductive surges. This makes it suitable for consumer and commercial electronics where transient voltage and noise immunity is essential.
