MALCE7.0A is a unidirectional current-limiting overvoltage protection device extensively used in various applications. It can be classified as a TVS-Diode. The MALCE7.0A has a clamping voltage of 7.0V and a surge absoption capability of 800 watts over a wide temperature range of -30 to + 110 degrees Celsius. The ultimate breakdown voltage (BVdss) is 8.0V.The Working Principle of the MALCE7.0A is to utilize the symmetrical structure of the TVS Diode to minimize capacitance variation at high frequency. The symmetrical structure also facilitates easier clamping of transients over a wide range of voltage and current levels. The TVS Diode contains two stacked devices, an absorber diode and a clamp diode. When a transient occurs, the absorber diode absorbs the transient energy whilst the clamp diode clamps the transient at a level so that external components are not damaged.The MALCE7.0A has many applications in power switching circuits and in products that require over-voltage/over-current protection. For example it can be used in power-inrush and over-voltage protection. It also provides excellent transient protection for amplifiers and for other audio components. Additionally it is also suitable for automotive applications, withstanding high voltage transients and temperatures.The MALCE7.0A is a robust, reliable and cost-effective device. Its symmetrical structure provides excellent capacitance variation at high frequency, as well as good clamping characteristics under transient conditions. It can withstand temperature extremes and is suitable for use in a variety of automotive and consumer applications. The MALCE7.0A is therefore an ideal choice for the protection of vulnerable electronic components from over-voltage and over-current transients.
