Ama-Diode ayizingxenye ze-elekthronikhi ezineziphetho ezimbili eziqhuba okwamanje ikakhulukazi ohlangothini olulodwa (i-asymmetric conductance);Inokumelana okuphansi ohlangothini olulodwa (okungcono zero) nokumelana okuphezulu kolunye uhlangothi (okungapheli).Ishubhu le-diode vacuum noma i-thermoelectron diode iyishubhu ye-vacuum enama-electrode amabili, i-cathode eshisayo nepuleti lapho ama-electron akwazi ukugeleza esuka ku-cathode eya epuleti ohlangothini olulodwa kuphela.I-semiconductor diode, uhlobo oluvame ukusetshenziswa kakhulu namuhla, i-crystalline semiconductor material ene-pn junction exhunywe kumatheminali amabili kagesi.

Umsebenzi ovame kakhulu we-diode ukuvumela i-current ukuthi idlule ohlangothini olulodwa (olubizwa ngokuthi i-direct direction ye-diode), kuyilapho ivinjelwa ngakolunye uhlangothi (okuphambene).Ngale ndlela, i-diode ingabhekwa njengenguqulo ye-electronic ye-valve yokubuyisela.Lokhu kuziphatha kwendlela eyodwa kubizwa ngokuthi ukulungisa futhi kusetshenziselwa ukuguqula i-alternating current (ac) ibe yamanje eqondile (dc).Ama-rectifiers, ngendlela yama-diode, angasetshenziselwa imisebenzi efana nokukhipha ukushintshashintsha kumasignali omsakazo kumamukeli womsakazo.

Kodwa-ke, ngenxa yezimpawu ze-voltage zamanje ezingaqondile ze-diode, ukuziphatha kwayo kungase kube yinkimbinkimbi kakhulu kunalesi senzo esilula sokushintsha.I-semiconductor diode iqhuba ugesi kuphela uma kukhona i-threshold voltage noma i-voltage yokufaka eya phambili (i-diode kuthiwa isesimweni sokuchelela phambili).Ukwehla kwamandla kagesi emikhawulweni yomibili ye-diode ebheke phambili kuyahluka kancane kuphela namanje futhi kuwumsebenzi wezinga lokushisa.Lo mphumela ungasetshenziswa njengenzwa yokushisa noma i-voltage yereferensi.Ukwengeza, lapho i-voltage ehlehlayo emikhawulweni yomibili ye-diode ifinyelela inani elibizwa ngokuthi i-voltage ye-breakdown, ukumelana okuphezulu kwe-diode nokugeleza okuhlanekezela kwehla ngokungazelelwe kube ukumelana okuphansi.

Izici zamanje ze-voltage zama-semiconductor diode zingenziwa ngendlela oyifisayo ngokukhetha impahla ye-semiconductor kanye nokwethula ukungcola kwe-doping kokubalulekile phakathi nenqubo yokukhiqiza.Lezi zindlela zisetshenziselwa ukwakha ama-diode akhethekile enza imisebenzi eminingi ehlukene.Isibonelo, ama-diode asetshenziselwa ukulawula i-voltage (ama-Zener diode), avikele amasekhethi ekukhuphukeni kwamandla kagesi aphezulu (ama-avalanche diode), ukushuna ngogesi izamukeli zomsakazo nethelevishini (ama-varator diode) ukuze kukhiqizwe ama-oscillation e-RF (tunnel diode), ama-Gunn diode, ama-IMPATT diode. , futhi akhiqize ukukhanya (ama-diode akhipha ukukhanya).Ama-tunnel diode, ama-Gunn diode, nama-IMPATT diode anokumelana okungalungile, okuwusizo kuma-microwave nokushintsha amasekhethi.

Kokubili ama-vacuum diode nama-semiconductor diode angasetshenziswa njengamajeneretha omsindo ohlakazayo.
