Brief the action principle that says diode

    If tell resistor, capacitance, inductance,3 large element are the word of our commonnest electron element, and diode is we see most semiconductor electron element. Why to say diode component of unlike resistor, capacitance, inductance electron of the semiconductor that be called that? Because diode is to use semiconductor data,this is what according to its charge has P pole to flow to N pole is characteristic and make, reason is called semiconductor electron component. The component such as canal of more powerful than its function dynatron, MOS also is semiconductor electron component.
     Diode has two pin, one is positive electrode one is negative pole, its biggest character is one-way conductivity, already charge can flow to negative pole by positive electrode only. The parameter with main diode has rated electric current, rated voltage, knot voltage to wait, choose Shi Yinggen according to asking actually to try to discriminate. Diode sort is very muti_function each different, have rectification diode commonly, stabilized voltage diode, glow diode.

    Rectification diode is to be used turn into AC of DC, is the quantitative component that uses diode according to place between single-phase commutate circuit: ? The; of circuit of complete wave commutate that? of Bian of Jian of  of ㄕ of argon of road of Nai of  of joyous  of ブ of Mei of take along sth to sb uses transformer take a percentage of a deal to add two diode and the bridge-type that use 4 diode to form work galvanic way. Cent of three-phase commutate circuit is circuit of commutate of complete bridge-type of half commutate circuit and three-phase. The relevant knowledge of these circuit all has between teaching material of general electron technology explain, the detail asks referenced and relevant data. The place that we see rectification diode applies when middling in the job has all sorts of electron facility primary commutate side, vacuum communication contactor is sucked add up to the rectification circuit before coil to wait. Our common rectification diode is the 1N4700 of the 1.5A that black model seals more- – 1N4707 series. Rectification diode uses circuit silver-colored annulus to indicate negative pole place in its surface commonly.
    Stabilized voltage diode is commonly used between the circuit that has particular demand to volts d.c. value. Stabilized voltage diode is to use diode retrorse puncture is characteristic and made component, its should notice most between circuit a bit already stabilized voltage diode should be used reversely, want to receive the negative pole of stabilized voltage diode the anode of power source namely, its anode receives the negative pole of power source, this want to remember well. Commonly used stabilized voltage diode has 1N4728- – 1N4769 series, 3.3v of limits of its stabilized voltage- – 100v. But the value of output electric current as a result of stabilized voltage diode is not great, reason is commonly used between the circuitry with working lesser electric current. In addition the stabilized voltage character that uses stabilized voltage diode is among concerned electron circuitry, it still is gifted to be restricted, voltage uses relative function.
    Glow diode is us in the job directive and daily illume are become the component of middling bring into contact with, we use LED of its English abbreviate to take the place of commonly point to it. Because high-power gives off light now the ceaseless emerge in large numbers of diode, it is very original Pu Liang, difficult already to exceed very bright, light classification method applicable. The working voltage of glow diode is commonly 2.5- – 4.5v left and right sides, in prep above its work the regular job that suitable step-down resistor talent should string together to ensure glow diode in the circuit of voltage. Glow diode is the element that has polarity likewise, the one aspect of the matter with longer pin of diode of glow of general cap type is positive electrode, high-power piece glow diode meets shape to grant polarity symbol designation in component weld commonly, when use or changing, want to notice.
   In addition diode is familial in the center the diode that still has a lot of sort such as demodulation diode, switch diode, laser diode, transfiguration diode. Everybody should read its parameter manual carefully when use and be overhauled. Anyhow, know and master diode this kind most semiconductor component of the foundation, be knowledge of our study electron surely the road of classics.
