TVS - Diodes

Transient Voltage Suppression (TVS) diodes are commonly used in electronic circuits to protect them against voltage transients or surges. Examples of such transient events are voltage spikes, lightning surges, and electric motors switching on and off. The P4KE56-E3/54 is a five lead unidirectional TVS diode that is used as a high current limiting component in a wide variety of applications that require overcurrent or over voltage protection. This component is composed of two silicon diodes with an integrated transient voltage suppressor.

Application Field

The application field of the P4KE56-E3/54 is quite wide, ranging from consumer electronics and telecommunications equipment to automotive and industrial electronic systems. Specifically, the device is used mainly in the protection of data lines and signal lines in computers, phone systems, communications systems, and audio/video systems. The device can also be used in the protection of automotive power systems, and in industrial control systems.

Working Principle

When a transient voltage spike or surge occurs the TVS diode will become forward biased and divert the surge current away from the protected component. The P4KE56-E3/54 has peak pulse power dissipation of 500 Watts, making it suitable for a wide variety of transient voltage protection needs. The device is also capable of limiting peak Surge currents up to 50A and tolerates continuous DC voltage of up to 18v. The component also offers a fast response time, making it ideal for situations where fast overvoltage protection is needed.
