TVS (Transient Voltage Suppression) diodes are an important class of components used in applications relating to controlling and protecting electronic components against over voltages. The MXLSMCG8.5CAE3 is a particular type of TVS diode which serves a variety of purposes in a wide range of different applications. This article will discuss the application fields and working principle of the MXLSMCG8.5CAE3.

Application Fields

The MXLSMCG8.5CAE3 is a diode designed for controlling voltage, protecting against over-voltage, and eliminating inductive kickback in a variety of different electronic circuitry. The diode is designed to be used in a wide range of applications, including in automotive, industrial, and consumer electronics. Examples of some of the applications which utilize the MXLSMCG8.5CAE3 are industrial communication and signaling, aerospace and military defense systems, 5V rail protection, automotive lighting, and AC and DC line filters.

The MXLSMCG8.5CAE3 is also commonly used in high-end consumer electronics, such as DVD players, AC/DC converters, hard drives, and LCD/LED displays. It is also used in medical equipment, such as infusion pumps and ECG monitoring devices. In these applications, the diode is primarily used to protect against electrical noise and unwanted voltage spikes.

Working Principle

The MXLSMCG8.5CAE3 is a two-terminal, piezoelectric device that is designed to help protect electronic equipment from transients and over-voltages. It consists of a semiconductor junction formed between two p-type and one n-type material. When applied voltage exceeds the threshold voltage of the diode, it switches from a reverse-biased condition to an abrupt forward-biased condition, allowing current to flow in the circuit. The advantage of this type of diode is that, unlike other diodes, it can withstand voltage transients better than standard diodes and can operate at much higher voltages.

When an overrunning surge of voltage is detected by the MXLSMCG8.5CAE3, the diode triggers an active element within the diode, which absorbs the surge energy and dissipates it. This energy is dissipated through a special absorber layer between the p-type and n-type material, releasing the energy in the form of heat, thus protecting the electronic component from the voltage surge.

In addition to controlling and protecting circuits from voltage surges, the MXLSMCG8.5CAE3 also helps prevent ESD (electrostatic discharge) by providing a low capacitive path around the component. This path helps to reduce the charge buildup that occurs when two materials with different electrical potentials come into contact. By dissipating the charge build-up, the diode helps protect the component from possible damage caused by ESD.

Conclusion

The MXLSMCG8.5CAE3 is an important type of transient voltage suppression diode used to protect electronic components from over voltages and transients. It is used in a variety of applications, including automotive, industrial, and consumer electronics, and helps protect against ESD as well. The diode operates on a two-terminal, piezoelectric principle, which triggers an active element when a surge is detected. This element absorbs the surge energy and dissipates it in the form of heat, protecting the electronic components from damage.
