Diode ke likarolo tse peli tsa elektronike tse tsamaisang hona joale haholo-holo ka tsela e le 'ngoe (asymmetric conductance);E na le khanyetso e tlase ka lehlakoreng le le leng (hantle ho zero) le khanyetso e phahameng ka lehlakoreng le leng (ka mokhoa o sa feleng).Tube ea vacuum ea diode kapa thermoelectron diode ke tube ea vacuum e nang le li-electrode tse peli, cathode e futhumetseng le poleiti eo lielektrone li ka phallang ho tloha ka cathode ho ea poleiti ka tsela e le 'ngoe feela.Semiconductor diode, mofuta o sebelisoang ka ho fetesisa kajeno, ke sesebelisoa sa crystalline semiconductor se nang le pn junction e hokahaneng le liteishene tse peli tsa motlakase.

Mosebetsi o tloaelehileng ka ho fetisisa oa diode ke ho lumella hore hona joale ho fete ka tsela e le 'ngoe (e bitsoang tataiso ea pele ea diode), ha e ntse e e thibela ka lehlakoreng le leng (ka morao).Ka tsela ena, diode e ka nkoa e le phetolelo ea elektronike ea valve ea ho khutla.Boitšoaro bona ba tsela e le 'ngoe bo bitsoa tokiso 'me bo sebelisoa ho fetolela alternating current (ac) ho ea ho ea hona joale (dc).Li-rectifiers, ka mokhoa oa diode, li ka sebelisoa bakeng sa mesebetsi e kang ho ntša modulation ho tsoa ho mats'oao a seea-le-moea ho moamoheli oa seea-le-moea.

Leha ho le joalo, ka lebaka la litšobotsi tse sa tloaelehang tsa motlakase oa diode, boitšoaro ba eona bo ka ba bo rarahaneng ho feta ketso ena e bonolo ea ho fetola.Semiconductor diode e tsamaisa motlakase ha feela ho e-na le motlakase oa monyako kapa motlakase o kenang ka tsela e eang pele (ho boleloa hore diode e sebakeng sa pele se leeme).Ho theoha ha motlakase lipheletsong tse peli tsa diode e leeme ho ea pele ho fapana hanyane le hona joale mme ke ts'ebetso ea mocheso.Phello ena e ka sebelisoa e le sensor ea mocheso kapa motlakase oa referense.Ho phaella moo, ha motlakase o ka morao lipheletsong tse peli tsa diode o fihla boleng bo bitsoang "breakdown voltage", khanyetso e phahameng ea diode ho phallo e khutlelang morao e theoha ka tšohanyetso ho ea ho khanyetso e tlaase.

Litšobotsi tsa hona joale tsa motlakase oa li-semiconductor diode li ka etsoa ka mokhoa o ikhethileng ka ho khetha thepa ea semiconductor le ho hlahisa litšila tsa doping ka thepa nakong ea ts'ebetso ea tlhahiso.Mekhoa ena e sebelisetsoa ho etsa diode tse khethehileng tse etsang mesebetsi e mengata e fapaneng.Ka mohlala, li-diode li sebelisetsoa ho laola motlakase (Zener diodes), ho sireletsa li-circuits ho tloha ho maqhubu a phahameng a matla (avalanche diode), li-radiode tse amohelang seea-le-moea le thelevishene (varator diode) ho hlahisa RF oscillations (tunnel diode), Gunn diode, IMPATT diode. , le ho hlahisa khanya (light-emitting diodes).Li-tunnel diode, li-Gunn diode, le IMPATT diode li na le khanyetso e mpe, e leng molemo ho microwave le li-circuits tsa switching.

Ka bobeli vacuum diode le semiconductor diode li ka sebelisoa e le lijenereithara tsa lerata la ho hasanya.
