Description
Technical field
The utility model belongs to a kind of photovoltaic diode in the technical field of semiconductor device.
Background technology
Photovoltaic diode is the important protection device of photovoltaic generating system; extensively with the supporting use of solar module, the while also can be applicable in the low pressure high frequency switch device, and in the power-supply system of computer, household electrical appliance, stored-program control exchange etc.; both can make rectification usefulness, and also can make clamp and use.Along with cleaning, pollution-free, reproducible solar energy development utilization, the develop rapidly of communication automatic technology and household electrical appliance, the application market of photovoltaic diode will constantly enlarge.
But the photovoltaic diode of prior art can not adapt to abominable outdoor environment for use, especially during the broiling summer, because thermal resistance height, poor radiation, the intensity of photovoltaic diode are low, so it very easily damages, influences the service behaviour of electrical appliance.
The utility model content
Technical problem to be solved in the utility model provides the photovoltaic diode of low, the easy heat radiation of a kind of thermal resistance, intensity height, long service life.
The utility model comprises package casing, schottky junction and two pins of being made by the novel aluminum material; The package casing of being made by the novel aluminum material comprises the package cavity of a bottom lock, and schottky junction is in the package cavity; One end of above-mentioned one of them pin is connected an end of schottky junction, and the other end of this pin runs through package cavity bottom and is in outside the package cavity; One end of another pin links to each other with the other end of schottky junction, and the extension of the other end of this pin is in outside the columned package cavity; Be filled with high heat conduction potting resin in the columned package cavity.
The package casing that adopts the novel aluminum material to make has advantages such as rapid heat dissipation, volume is little, intensity is high, thermal resistance is low, and can reduce junction temperature effectively.Simultaneously, the high heat conduction packaging plastic that adopts the vacuum high-temperature curing technology to fill can closely contact with thermal conductive shell, and this has not only improved the intensity of product, and has reduced thermal resistance, helps heat radiation.Photovoltaic diode of the present utility model has not only kept characteristics such as the big operating current, low forward voltage drop, high-frequency and low-consumption, high surge current, transient protective function of prior art photovoltaic diode; promote the performance index of its operating ambient temperature and junction temperature simultaneously, met or exceeded the new related standards of formulating of photovoltaic industry.
