Abstract

The invention relates to a rectifier diode module which comprises a bottom plate, two ceramic chips are arranged on the bottom plate, two mounting holes are respectively formed in the left end and theright end of the bottom plate, a group of copper-clad areas are set on the ceramic chips, and extraction electrodes are arranged on the copper-clad areas in a rectifying circuit mode, and the rectifier diode module also comprises a group of bare chips set on the ceramic chips according to a rectifying circuit and aluminum wires which are bonded between the bare chips and the copper-clad areas. The rectifier diode module can effectively solve the problems that an existing rectifier diode module is connected in a bridge connection mode, the stress is high, a chip is prone to damage, and the service life is shortened.

Description

technical field [0001] The invention relates to a rectifying diode module. Background technique [0002] In the prior art, the structure of the rectifier diode module basically includes a housing, components such as lead-out electrodes, copper connecting plates, bridges, diode chips, chip protection glue, ceramic copper-clad laminates, and copper bottom plates set in the housing. At the same time, lead-out electrodes, copper connecting plates, connecting bridges, diode chips, ceramic copper-clad laminates and copper base plate groups are packaged in the housing through epoxy resin. [0003] However, the connection through the bridge method has the problems of high stress, easy damage to the chip, and shortened service life. Contents of the invention [0004] The purpose of the present invention is to provide a rectifier diode module, which solves the problems that the existing rectifier diode modules are connected through a bridge, which has high stress, easily damaged ch...
