    1. The switching diode uses the unidirectional conductivity of the diode. After the semiconductor PN junction is added with a forward bias, the resistance is small (tens to hundreds of ohms) in the on state; after the reverse bias is added At the end, its resistance is very large (the silicon tub...Read more »

    What is the role of the triode: the triode has a current amplification effect, which is essentially that the triode can control the large amount of change in the collector current with a small amount of change in the base current. This is the most basic and important feature of a triode. We refer...Read more »

    There are two types of crystal triodes (hereinafter referred to as triodes) according to materials: tantalum tubes and silicon tubes. Each of them has two structural forms, NPN and PNP, but the most commonly used are silicon NPN and 锗PNP triodes (where N is the addition of phosphorus in high-pur...Read more »

    1. According to the luminous color of the luminous tube  According to the color of the luminous tube, it can be divided into red, orange, green (subdivided into yellow-green, standard green and pure green), blue light and so on. In addition, some light-emitting diodes include chips of two or thre...Read more »

  • What is a diode?
    Post time: Aug-02-2019

    Diode, among electronic components, a device with two electrodes that allows current to flow only in a single direction, many of which are used for its rectification function. The varactor is used as an electronically tunable capacitor. The current directionality of most diodes is often referre...Read more »

  • The simplest diode form – AP-N connector
    Post time: Aug-02-2019

    The diode acts as a valve in an electronic circuit. The AP-N connector is the simplest form of diode. When it is forward biased, it behaves as an ideal short circuit and acts as an ideal open circuit in reverse bias. In addition to simple PN junction diodes, although the basic principles are ro...Read more »

  • How do diodes work?
    Post time: Aug-02-2019

    The crystal diode is a pn junction formed by p-type semiconductor and n-type semiconductor, which forms a space charge layer on both sides of the interface and has its own electric field. When there is no applied voltage, the diffusion current caused by the carrier concentration difference on bo...Read more »
