TVS diodes provide protection from transient voltage surges and are found in numerous spaces where electrical components are exposed to damaged from external sources, such as lighting strikes, tension switching, electrostatic discharges, and RF emissions. The MART100KP280CA, which is a type of TVS diode, offers a whole host of benefits and is widely used in a variety of applications. This article will discuss the application field and working principle of the MART100KP280CA.

Application Field

The MART100KP280CA is designed to provide protection for almost any kind of electrical component, including those found in cell phones, cell towers, PDAs, digital cameras, computers, and industrial equipment. This diode is able to protect circuit components from spikes in voltage up to 8.2 KV, and is rated to 35 A of current. As such, it is often used as a primary surge suppression component for circuit protection.

The diode is especially noted for its ability to withstand intermittent high pulses with very low leakage current. Its small size also makes it suitable for miniaturized applications such as USB ports, laptop chargers, and other mobile devices. In addition, its 3-pin SOD-323F package is suitable for high-density SMD dipping, making it an ideal choice for mass production.

Working Principle

The MART100KP280CA is a 1-line bidirectional device which means that it can conduct in both directions (positive and negative). When there is a surge or spike of voltage, the diode begins to conduct and divert the current away from the protected circuit, thus preventing any damage. This is done by the diode\'s breakdown voltage, which is determined by its Zener voltage ratings.

Once the surge or spike has passed, the diode will trip and reset itself. This resetting mechanism is also known as "nonlinear clipping". During resetting, the diode will return to its regular or normal state. Once this happens, the diode will be able to conduct even higher voltages than it did before.

In order for the diode to operate correctly, it is important to correctly install and handle it. This includes correctly connecting the diode to voltage/ground sources, as well as current rating requirements. It is also important to make sure that the diode is not exposed to extreme temperatures or moisture levels, as this can affect its ability to protect the circuit.

Conclusion

The MART100KP280CA is a type of TVS diode which is used to provide protection for electrical components from voltage surges. It is capable of providing protection up to 8.2 KV and is rated to 35 A of current. Furthermore, it features a unique resetting mechanism which allows it to return to its normal state after protection. When correctly installed and handled, the diode can effectively protect the circuit from damage due to surges and spikes.
