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.

商(shang)品介紹(shao)
貼片二極管(guan)又(you)稱(cheng)晶體(ti)二(er)極管,簡稱二極(ji)管，別的(de)，還有早期(qi)的真(zhen)空電子二極管;它(ta)是(shi)一(yi)種具(ju)有單(dan)向(xiang)傳導電流的電子器件(jian)。在半(ban)導(dao)體二極管內部有一個(ge)PN結(jie)兩(liang)個引線端子，這種(zhong)電子器(qi)件依(yi)照外(wai)加電壓的方向，具有單向電流(liu)的轉導性。一般(ban)來講(jiang)，貼(tie)片(pian)晶體二極管是一個由p型半導體和n型半導體燒結構(gou)成的p-n結界(jie)麵(mian)。在其界麵的兩邊構成空間電荷層，構成(cheng)自(zi)建電場。當(dang)外加電壓(ya)等於零時，因(yin)為p-n 結兩邊(bian)載(zai)流子的濃(nong)度差(cha)導致分(fen)散(san)電流和(he)由(you)自建電場(chang)導致(zhi)的漂(piao)移(yi)電流相等(deng)而處於(yu)電平(ping)衡(heng)狀(zhuang)態，這(zhe)也(ye)是常態(tai)下的二極管特性。

貼片二極管的管壓降:矽二極管(不發光類型)正(zheng)向管壓降(jiang)0.7V，鍺管正(zheng)向管壓降(jiang)為0.3V，發光二極管正(zheng)向管壓降(jiang)會隨不一樣發光色彩而不一樣。主(zhu)要(yao)有三(san)種色彩，詳細(xi)壓降參考(kao)值(zhi)如下:赤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(chang)發光時的額定(ding)電流約(yue)為20mA。貼片二極管的電壓與(yu)電流不是線性(xing)關係(xi)，所以在將(jiang)不一樣的貼片二極管並聯(lian)的時候(hou)要接相適(shi)應的電阻。 貼片二極管特(te)性 貼片二極管，電子元件旁(pang)邊，一種具有兩個電極的設備(bei)，隻(zhi)允(yun)許(xu)電流由單一方向流過(guo)。許多(duo)的使用(yong)是使(shi)用其(qi)整流的功(gong)用。而變容(rong)二極管(Varicap Diode)則(ze)用來當作電子式的可調電容器。
