Description
Technical field
The utility model relates to rectistack, relates in particular to a kind of small-sized wire-jumper type biserial bridge heap of AC-DC.
Background technology
The bridge architecture that bridge rectifier is made up of four rectifier diodes; It utilizes the unilateal conduction characteristic of diode that alternating current is carried out rectification; Because bridge rectifier must utilize efficient to double than halfwave rectifier to input sine wave; Be a kind of remarkable improvement, convert in the galvanic circuit so be widely used in alternating current to the diode halfwave rectifier.
Along with electronic product develops to miniaturization, what require that the profile of semi-conductor electronic device does is again little and thin.Present minimize bridge heap mainly is divided into two types, and one type is direct insertion bridge heap, and another kind is SMD bridge heap.
For SMD bridge heap; More typical structure has following several kinds at present: 1, the disclosed a kind of miniature semiconductor rectifier bridge of Chinese invention patent publication number CN1197989A; It comprises two diode crystal grain that have the N type altogether and the two diode crystal grain that have the P type altogether; Wherein altogether a p type island region of N type crystal grain together a corresponding N type fauna of P type crystal grain be connected to a terminal electrode of first group of lead frame, altogether another p type island region of N type crystal grain then together another N type district of P type crystal grain be connected to the another terminal electrode of first group of lead frame, and altogether N type crystal grain N type district together the p type island region of P type crystal grain then be connected to the two-terminal electrode of second group of lead frame respectively; Thereby constitute a bridge rectifier; Although this miniature rectifier structurally helps microminiaturization, make the double diode chip that upward needs to adopt two kinds, promptly have N type double diode chip altogether and have P type double diode chip altogether; Cause following problem easily: 1) acp chip is wide in variety, and complex process shape increases; 2) the chip qualification rate is relatively low; 3) owing to there are two chip kinds, uniformity is relatively poor; 4) chip of P type substrate relatively difficulty do.2, the disclosed plate mini-type bridge heap of Chinese utility model patent Granted publication CN2545706Y; It forms bridge rectifier by four rectifier diodes in a packaging body, four rectifier diodes are made up of identical PN junction chip; Spatially two and be listed in of four PN junction chips; Two and be listed in down in addition, the p type island region of each PN junction chip and N type district arrange that up and down wherein the p type island region of diagonal position PN junction chip is identical with orientation, N type district; Adopt a connecting piece to connect between two PN junction chips repeatedly putting up and down respectively; And be listed in and be listed under two PN junction chips adopt another brace to be connected respectively, two braces on the intermediate layer are as one group of electrode terminal, two braces on the upper and lower are organized electrode terminal as another; And in packaging body, draw respectively, constitute miniature five layers of rectifier bridge pile structure with this.Because this patent adopts five-layer structure; Its thickness of product is generally about 2.5～2.7mm; The inner many accommodation spaces of electronic product have not only been taken; And, proposed higher requirement for simultaneously each layer parts installing and locating because the processing step that is arranged so that the production and processing of bridge heap of sandwich construction increases.
Four crystal grain both positive and negative polarities of existing in addition SMD bridge heap are not to be positioned at same direction, and when causing encapsulation like this, the crystal grain difficulty of arranging confounds easily, therefore need take a long time crystal grain is sorted, and makes production efficiency reduce.
