Abstract

The invention relates to a varistor adopting a novel base pin design method. The varistor is characterized in that it has multiple base pins, the positions and quantity of the base pins can be obtained through calculation and electric current density simulation, when the input end and output end have more than one base pin, they can be connected by an electrode slice. With the design, without changing the area and volume of an original varistor substrate, electric current fully flows through the filling substance in the varistor, thus enhancing the varistor flow capacity, impact resistance and other characteristics, and improving the varistor service life and protection grade.

Description

technical field [0001] The invention belongs to the field of electrical and electronic components. Mainly for varistors, change the pin structure to make the flow performance better. Background technique [0002] Varistor is a voltage-sensitive non-linear overvoltage protection semiconductor element. It can be divided into many types according to its structure, manufacturing process, materials used, and volt-ampere characteristics. Common varistor devices are metal oxide voltage Varistors, especially zinc oxide varistors. Different from ordinary resistors, varistors are made according to the nonlinear characteristics of semiconductor materials. Ordinary resistors obey Ohm's law, while the voltage and current of varistors have a special nonlinear relationship. When the voltage applied across the varistor is lower than the nominal rated voltage value, the resistance value of the varistor is close to infinity, and there is almost no current flowing inside, which is equivalent...
