TVS - Diodes: P4KE24CAHA0G application field and working principle

TVS - Diodes are the acronym for transient voltage suppressors, which are also known as transient voltage suppression diodes. These diodes are very effective in reducing the transmission of voltages that can have a significant impact on electronic components.

The P4KE24CAHA0G is a unidirectional TVS diode which is designed to protect electronic devices from high voltage transients. This device is capable of handling a maximum breakdown voltage of 24Volts. It has a maximum peak pulse power rating of 600W. The device has a maximum clamping voltage of 35V and a clamping current of 48A.

Application Field of P4KE24CAHA0G

The P4KE24CAHA0G is ideal for applications that require high voltage protection, such as power supplies, circuits dealing with power electronics, automotive systems, telecommunications and more. Its application includes but not limited to protection of input ports of data communication devices, power supplies, drives, ITE, DC motors, protection of micro-processors, PCs and peripherals.

Working Principle of P4KE24CAHA0G

The P4KE24CAHA0G working principle is based on a metal–oxide–semiconductor field-effect transistor (MOSFET). When a high voltage transient occurs, the MOSFET gate capacitance switches swiftly from its off to on state, allowing a current surge to pass through the diode. This current surge tends to be limited to a desirable amount bypassing through the TVS diode by its clamping voltage and current. While the diode is clamped, its internal structure absorbs the excess charge to reduce the transient voltage. This process of limiting and dissipating the energy of the transient voltage not only protects the device from high voltage transients but also prevents it from malfunctioning.
