Sebakeng sa lisebelisoa tsa elektronike, li-diode li ema e le likarolo tsa motheo tse laolang ho phalla ha motlakase. Har'a mefuta e fapaneng ea li-diode, li-diode tsa Zener li na le boemo bo ikhethang, bo khetholloang ke bokhoni ba tsona ba ho laola motlakase le ho sireletsa li-circuits tse hlokolosi. Tataiso ena e felletseng e shebana le lefats'e la diode tsa Zener, e fang ba qalang kutloisiso e felletseng ea ts'ebetso ea bona le ts'ebeliso ea bona.
Li-Diode tsa Zener tse nyenyefatsang
Li-diode tsa Zener, tse tsejoang hape e le li-diode tsa ho senyeha, ke lisebelisoa tsa semiconductor tse bonts'ang tšobotsi e itseng ea ho senyeha ha motlakase. Ha li le tlas'a matla a morao-rao a leeme a fetang matla a tsona a senyehang, li-diode tsa Zener lia senyeha, li lumella hore hona joale ho phalle ka lehlakoreng le ka morao. Ketsahalo ena e laoloang ea ho senyeha e theha motheo oa ts'ebetso ea bona e tsotehang.
Mokhoa o sebetsang oa Zener Diode
Ts'ebetso ea diode ea Zener e ipapisitse le mohopolo oa phello ea ho senyeha ha Zener. Ha motlakase o ka morao ho diode oa Zener o ntse o atamela matla a eona a ho senyeha, sebaka sa motlakase se ka har'a diode sea matlafala. Motlakase ona o matla o senya lielektrone ho tloha linaheng tsa bona, ho li nolofalletsa ho tsamaisa motlakase ka lehlakoreng le ka morao. Ho phatloha hona ha lielektrone ho etsa ketsahalo ea ho senyeha ha Zener.
Litšobotsi tsa bohlokoa tsa Zener Diode
Li-diode tsa Zener li khetholloa ke likarolo tse 'maloa tsa bohlokoa tse hlalosang boitšoaro le ts'ebetso ea tsona:
Zener Voltage (Vz): Tšobotsi e hlalosang ea diode ea Zener, motlakase oa Zener o emela motlakase o ka morao oa bias moo phello ea Zener e senyehang e hlahang.
Zener Impedence (Zz): Zener impedance e bolela khanyetso e fanoang ke Zener diode ha e sebetsa sebakeng sa eona se robehileng.
Phallo ea Matla (Pd): Ho senya matla ho bolela matla a mangata ao diode ea Zener e ka sebetsanang le eona ntle le ho chesa kapa ho senya.
Lisebelisoa tsa Zener Diodes
Li-diode tsa Zener li fumana mesebetsi e atileng lipotolohong tse fapaneng tsa elektroniki ka lebaka la thepa ea tsona e ikhethang:
Taolo ea Voltage: Li-diode tsa Zener li sebetsa hantle haholo ho boloka motlakase o tsitsitseng ho pholletsa le mojaro ka ho sebetsa joalo ka litšupiso tsa motlakase.
Tšireletso ea Overvoltage: Li-diode tsa Zener li sireletsa likaroloana tse nang le kutloelo-bohloko ka ho thiba motlakase o feteletseng fatše nakong ea ho phahama kapa li-spikes.
Voltage Clamping: Li-diode tsa Zener li ka fokotsa maemo a phahameng kapa a tlase a motlakase potolohong, ho thibela ho sotha ha lets'oao.
Waveform Shaping: Li-diode tsa Zener li ka bopa liforomo tsa maqhubu ka ho khaola kapa ho lokisa matšoao a AC.
Qetello
Li-diode tsa Zener, tse nang le bokhoni bo hlollang ba ho laola motlakase le ho sireletsa potoloho, li fetohile likarolo tsa bohlokoa meralong ea elektroniki. Ho feto-fetoha ha tsona le katleho ea tsona li li etsa matlotlo a bohlokoa mefuteng e mengata ea ts'ebeliso, ho tloha ho li-voltage tse bonolo ho ea ho li-circuits tsa ts'ireletso tse tsoetseng pele. Ha u ntse u kena leetong la hau lefatšeng la lisebelisoa tsa elektroniki, ho utloisisa diode tsa Zener e tla ba letlotlo la bohlokoahali.
