Abstract

The invention relates to a piezoresistor based on a novel pin design method. The piezoresistor is characterized by being provided with a plurality of pins; the positions and the number of the pins can be obtained by calculation and current density simulation; more than one input end or more than one output end can be connected by an electrode plate. Due to adoption of the design, current can fully pass through the material added into the piezoresistor on the premise that the area and the volume of the original piezoresistor substrate are not changed, so that such properties of the piezoresistor as flow capacity and impact resistance can be improved, the service life of the piezoresistor is prolonged, and the protection level of the piezoresistor is improved.

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...
