TVS (transient voltage suppression) varistors, MOV (metal oxide varistors) and surge protectors are part of the same electrical technology and used in a similar way. One of the most important and common types of TVS and MOV protection is the EZA-EG2A50AX which is generally applied to overvoltage spike suppression. It can widely be used to suppress standard transient voltage and temporarily overvoltage caused by component failure, soldering errors or external electrical fields such as lightning. This article will discuss the application fields and working principle of the EZA-EG2A50AX.The application fields for the EZA-EG2A50AX include computer and power systems, cell phone systems as well as LED and automotive electronics. The EZA-EG2A50AX is also suitable for communications and control systems, audio and visual systems, as well as outdoor equipment. The main purpose of the EZA-EG2A50AX is to provide overvoltage protection through which electrical surges such as those caused by lightning strikes can be detected and diverted. This protection guards against surges in both AC and DC applications.The working principle of the EZA-EG2A50AX begins with a PTC (positive temperature coefficient) thermistor that acts as a current limiting resistor which is made up of glass or quartz and a metal reflector which also functions as a heat shield. When a surge occurs, the thermistor absorbs the surge energy and generates a large amount of heat which is then removed by the aluminum reflector. When the thermal protection point is exceeded, the thermistor quickly heats up and provides a fast reaction time which prevents short circuits and other damages that can be caused by an overload.The EZA-EG2A50AX also includes a low-frequency EMI filter which reduces noise, and a MOV (metal oxide varistor) which provides a versatile voltage and temperature protection range for alternating current or direct current. The MOV absorbs excess spike energy while providing a path to ground and dissipates this energy increasing the antecedent voltage peak. This provides an effective protection against electrical noise, lightning and other short unexpected overvoltage occurrences.The EZA-EG2A50AX is considered to be one of the best surge protection devices available in the market due to its high efficiency and reliability and is widely used in various applications. It is a must-have device for preventing costly damages that can be caused by unexpected overvoltage and can be used in a variety of applications such as computers, communications equipment, cell phones, LED and automotive electronics. By understanding the application fields and working principle of the EZA-EG2A50AX, users can be ensured that their connected equipment will be adequately protected from any kind of overvoltage.
