Abstract

The invention discloses a fast recovery diode chip structure. The fast recovery diode chip structure comprises an upper sealing cover, a lower sealing cover and a chipset, the chipset comprises a plurality of chips and welding sheets among the plurality of chips, first locking blocks are fixedly connected to the two ends of the upper sealing cover, second locking blocks are fixedly connected to the two ends of the lower sealing cover, locking rods are inserted between the first locking blocks and the second locking blocks, one end of each locking rod is fixedly connected with a fixing block, the other end of each locking rod is fixedly connected with a fixing sleeve, a first pin is inserted into one side of the upper sealing cover, and a first connecting piece is arranged at the end, located in the upper sealing cover, of the first pin. The fast recovery diode chip structure is simple and reasonable in construction, convenient to weld, low in manufacturing cost, high in percent of pass, convenient to disassemble, assemble and maintain and suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of diode-related products, in particular to a fast recovery diode chip structure. Background technique [0002] At present, the domestic fast diode technology is relatively mature, but the ultra-fast recovery diode (less than 150ns) technology lag is limited, especially the ultra-fast soft recovery diode has almost no batch independent products, which cannot meet the needs of high-frequency and high-efficiency power supplies. Therefore, to speed up the research on high-power ultra-fast soft recovery diodes and improve the localization of high-end traditional devices, it is necessary to further accelerate the process. [0003] However, the existing fast recovery diode chip structure is cumbersome to weld, inconvenient to assemble and disassemble, and takes a lot of time to overhaul, which has certain defects. Contents of the invention [0004] The purpose of the present invention is to provide a fast recovery diode ...
