Description

technical field [0001] The invention relates to the technical field related to diodes, in particular to a high-efficiency diode detection device. Background technique [0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode conducts. When a reverse voltage is applied to the anode and cathode, the diode is turned off. Therefore, the on and off of the diode is equivalent to the on and off of the switch. [0003] Generally, after the production of diodes is completed, in order to ensure the quality of the product, it is necessary to perform performance testing on the product, including the positive and negative resistance values, and the correctness of the positive and negative pole marks. The traditional testing is manual testing, usually using a multimeter manually. Detect the positive and nega...
