二極管種類有很多，按照所用的半導(dǎo)體材料，可分為鍺二極管（Ge管）和硅二極管（Si管）。根據(jù)其不同用途，可分為檢波二極管、整流二極管、穩(wěn)壓二極管、開關(guān)二極管、隔離二極管、肖特基二極管、發(fā)光二極管、硅功率開關(guān)二極管、旋轉(zhuǎn)二極管等。按照管芯結(jié)構(gòu)，又可分為點(diǎn)接觸型二極管、面接觸型二極管及平面型二極管。點(diǎn)接觸型二極管是用一根很細(xì)的金屬絲壓在光潔的半導(dǎo)體晶片表面，通以脈沖電流，使觸絲一端與晶片牢固地?zé)Y(jié)在一起，形成一個(gè)“PN結(jié)"。由于是點(diǎn)接觸，只允許通過(guò)較小的電流（不超過(guò)幾十毫安），適用于高頻小電流電路，如收音機(jī)的檢波等。面接觸型二極管的“PN結(jié)"面積較大，允許通過(guò)較大的電流（幾安到幾十安），主要用于把交流電變換成直流電的“整流"電路中。平面型二極管是一種特制的硅二極管，它不僅能通過(guò)較大的電流，而且性能穩(wěn)定可靠，多用于開關(guān)、脈沖及高頻電路中。
