Description
Technical field
The present invention relates to rectistack, relate in particular to a kind of small-scale jumper-type double-row bridge rectifier of AC-DC.
Background technology
The bridge architecture that bridge rectifier is comprised 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 to the diode halfwave rectifier, convert in the galvanic circuit so be widely used in alternating current.
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 classes, and a class is direct insertion bridge heap, and another kind is SMD bridge heap.
For SMD bridge heap, more typical structure has following several at present: 1, the disclosed a kind of miniature semiconductor rectifier bridge of Chinese invention patent publication number CN1197989A, it comprises the two diode crystal grain that have 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 the N-type district of N-type crystal grain together the p type island region of P type crystal grain then be connected to respectively the two-terminal electrode of second group of lead frame, thereby consist of a bridge rectifier, although this miniature rectifier structurally is conducive to microminiaturization, but need to adopt the double diode chip of two kinds in the manufacturing, namely have N-type double diode chip altogether and have P type double diode chip altogether, cause easily following problem: 1) acp chip is wide in variety, and complex process shape increases; 2) chip yield 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 sheet type miniature bridge stack of Chinese invention patent Granted publication CN2545706Y, it is in a packaging body, form bridge rectifier by four rectifier diodes, four rectifier diodes are made 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 up and down, wherein the p type island region of diagonal position PN junction chip is identical with orientation, N-type district, adopt respectively a connecting piece to connect between two PN junction chips repeatedly putting up and down, and be listed in and be connected two PN junction chips under being listed in and adopt respectively another brace to connect, 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 draw in packaging body respectively, consist of miniature five layers of rectifier bridge stack structure with this.Because this patent adopts five-layer structure, the thickness of its product is generally about 2.5～2.7mm, the inner many accommodation spaces of electronic product have not only been taken, and because the processing step that is arranged so that the production and processing of bridge heap of sandwich construction increases, the location is installed for simultaneously each layer parts and has proposed higher requirement.
Four crystal grain both positive and negative polarities of existing SMD bridge heap are not to be positioned at same direction in addition, and when causing like this encapsulation, the crystal grain difficulty of arranging confounds easily, therefore need to take a long time crystal grain is sorted, so that production efficiency reduces.
