Chip diode tube voltage drop: Silicon diode (non-light-emitting type) forward tube voltage drop 0.7V, germanium tube forward tube voltage drop to 0.3V, LED forward tube voltage drop will vary with different light-emitting colors. There are three main colors, and the detailed voltage drop reference values are as follows: the voltage drop of the red LED is 2.0murmur2.2V, the voltage drop of the yellow LED is 1.8V-2.0V, the voltage drop of the green LED is 3.0V-3.2V, and the rated current during normal light emitting is about 20mA. The voltage and current of the patch diodes are not linear, so it is necessary to connect the corresponding resistors when the different patch diodes are connected in parallel. Chip diode characteristics next to the chip diode, electronic components, a device with two electrodes that only allows current to flow in a single direction. Many uses use its rectification function. The varactor (Varicap Diode) is used as an electronic adjustable capacitor.

貼片二極(ji)管(guan)又(you)稱(cheng)晶(jing)體(ti)二極管,簡(jian)稱二(er)極管，別(bie)的(de)，還有(you)早(zao)期的真(zhen)空電子二極管;它是一種具(ju)有單(dan)向(xiang)傳導電流(liu)的電子器件。在半(ban)導(dao)體二極管內部(bu)有一(yi)個(ge)PN結兩個引線端(duan)子，這(zhe)種電(dian)子器(qi)件(jian)依照(zhao)外(wai)加(jia)電壓(ya)的方向，具有單向電流的轉(zhuan)導性。一般(ban)來講(jiang)，貼片晶體二極管是一個由(you)p型(xing)半導體和(he)n型半導體燒(shao)結(jie)構成(cheng)的p-n結界麵(mian)。在其(qi)界(jie)麵的兩邊(bian)構成空(kong)間電荷(he)層，構(gou)成自(zi)建(jian)電場。當外加電壓等於(yu)零時，因(yin)為(wei)p-n 結兩(liang)邊載(zai)流子的濃(nong)度差導致(zhi)分散電流和由自建電場導致的漂(piao)移(yi)電流相(xiang)等(deng)而處於電平(ping)衡(heng)狀(zhuang)態，這也(ye)是常(chang)態下(xia)的二極管特(te)性(xing)。

貼片二極管的管壓降:矽二極管(不發(fa)光(guang)類型)正(zheng)向管壓降0.7V，鍺管正(zheng)向管壓降為0.3V，發光二極管正(zheng)向管壓降會隨不一樣發光色彩而不一樣。主(zhu)要有三(san)種(zhong)色彩，詳細壓降參考值(zhi)如(ru)下:赤(chi)色發光二極管的壓降為2.0--2.2V，黃(huang)色發光二極管的壓降為1.8-2.0V，綠(lv)色(se)發光二極管的壓降為3.0-3.2V，正常發光時的額(e)定(ding)電流約(yue)為20mA。貼片(pian)二極管的電壓與電流不(bu)是線性關係，所以(yi)在將不一樣的貼(tie)片二極管並聯(lian)的時候要接(jie)相適(shi)應的電阻。 貼片二極管特性 貼片二極管，電子元件旁(pang)邊，一種具有兩個電極的設備，隻(zhi)允(yun)許(xu)電流由單一方向流過(guo)。許多(duo)的使(shi)用(yong)是(shi)使用其整(zheng)流的功用。而(er)變(bian)容(rong)二極管(Varicap Diode)則用來(lai)當(dang)作電子式(shi)的可調電容器。
