Description
Technical field
The utility model relates to a kind of point-contact type rectifier diode, belongs to technical field of semiconductors.
Background technology
Diode is one of the most frequently used electronic component, its maximum characteristic is exactly unilateal conduction, namely electric current flows through with a direction from diode only, and the effect of diode has rectification circuit, detecting circuit, voltage stabilizing circuit, various modulation circuit, is mainly all made up of diode, and its principle is all very simple, just because of the invention of the elements such as diode, just there is the birth in our the present colourful electronic information world.
There is following weak point in existing diode:
1) pin is easily by bending or fracture;
2) pin easily inserted when inlaying deeply, caused welding built on the sand.
These weak points have all had a strong impact on the useful life of diode.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art part, provides a kind of point-contact type rectifier diode.
Point-contact type rectifier diode of the present utility model, comprise anode tap (1), cathode leg (2), PN junction (3), N-type germanium wafer (4), support (5), metal touches silk (6) and shell (7), described anode tap (1) and N-type germanium wafer (4) are connected in the two ends that metal touches silk (6), described N-type germanium wafer (4) and support (5) are connected in the two ends of PN junction (3), described cathode leg (2) is connected with support (5), described PN junction (3), N-type germanium wafer (4), support (5) and metal touch silk (6) and are all located in shell (7), described anode tap (1) and the outside of cathode leg (2) are covered with adhesive layer (8) and albata layer (9) successively.
Preferably,
Described anode tap (1) and cathode leg (2) are provided with locating piece (10).
Point-contact type rectifier diode of the present utility model has following technique effect:
1) pin is not easy by bending or fractures;
