二極管是用半導體材料(硅、硒、鍺等)制成的一種電子器件。它具有單向導電性能，即給二極管陽極和陰極加上正向電壓時，二極管導通。當給陽極和陰極加上反向電壓時，二極管截止。因此，二極管的導通和截止，則相當于開關的接通與斷開。二極管是早誕生的半導體器件之一，其應用非常廣泛。
二極管就是由一個PN結加上相應的電極引線及管殼封裝而成的。采用不同的摻雜工藝，通過擴散作用，將P型半導體與N型半導體制作在同一塊半導體(通常是硅或鍺)基片上，在它們的交界面就形成空間電荷區(qū)稱為PN結。由P區(qū)引出的電極稱為陽極，N區(qū)引出的電極稱為陰極。因為PN結的單向導電性，二極管導通時電流方向是由陽極通過管子內部流向陰極。
二極管有兩個電極，由P區(qū)引出的電極是正極，又叫陽極;由N區(qū)引出的電極是負極，又叫陰極。三角箭頭方向表示正向電流的方向，二極管的文字符號用VD表示。
二極管的種類很多，分辨正負極的方法也不盡相同。以下小編列舉了幾種二極管正負極的判斷方法，僅供參考。
