VE24M00421K--

The VE24M00421K is a type of TVS (Transient Voltage Suppressor) device, more specifically classed as a Varistor or MOV (Metal Oxide Varistor). Its purpose is to protect electronic systems from voltage transients or spikes in power supply or signal circuits. Varistors are non-linear resistors, typically in the form of thin discs; they allow the voltage across them to be clamped at a predetermined level to protect the system from over-voltage.

VE24M00421K is a specific type of Varistor used for transient or surge protection. It is a unidirectional device, meaning that it can only direct the transient current safely away from the system. The VE24M00421K is designed to be installed in power supplies, automotive and audio-visual equipment, computers, telecommunication systems, and other electrical components or devices. It is a component of the surge protection device and is designed to protect delicate components from the damaging effects of electrical spikes.

The VE24M00421K consists of a metal oxide element and electrodes that are attached to the anode and cathode. The metal oxide element is a special non-linear semiconductor material that has a very large resistance when a low voltage is applied. However, when voltage reaches a certain level, the element suddenly switches to a very low resistance, which diverts the high-voltage current away from the protected element. This action limits the voltage across the protected element and helps to ensure it is not damaged. The function of the electrodes is to conduct the current from the element to the protected system.

The working principle of the VE24M00421K is quite simple. When a high voltage is applied to the electrodes, the metal oxide element begins to conduct current and provides a path for the high voltage current to be diverted away from the protected system. The large resistance prevents the current from passing through the protected system, thus safe-guarding it from the damaging effects of overvoltage.

The VE24M00421K is designed to handle transients up to a certain level, and is rated for a maximum voltage of 400V and a surge current of 10A. It has a clamping voltage of 24V and is designed for operation in temperatures ranging from -40ºC to 85ºC. It is available in a range of power ratings to meet the requirements of various applications. The VE24M00421K is also a RoHS compliant component, meaning it is designed to meet certain environmental standards.

In conclusion, the VE24M00421K is a unidirectional, non-linear device designed to protect sensitive components from the damaging effects of electrical surges or voltage transients. It can be used in a variety of applications and is available in a range of power ratings to suit different requirements. The device works by diverting the surge current away from the protected component, thus safe-guarding it from the effects of overvoltage.
