The invention provides an over-temperature protection method and structure of a nano-alloy electrode varistor, and belongs to the technical field of semiconductor ceramics. The upper surface of the zinc oxide piezoresistor is connected with an over-temperature protection temperature controller through gluing; the over-temperature protection temperature controller comprises a square temperature fuse; the packaging layer wraps the zinc oxide piezoresistor and the over-temperature protection temperature controller; in the using process of the piezoresistor, under the condition of overvoltage or over-temperature, a circuit is automatically cut off, the piezoresistor and the circuit are protected, the production process is simple, the consistency is good, and the reliability is high; the invention relates to a pressure-sensitive resistor with temperature protection, and solves the problems of poor welding, low product reliability and low product yield caused by the fact that the welding temperature is extremely di
