Ezweni eliyinkimbinkimbi lama-electronics, ama-diode abusa kakhulu njengezingxenye ezibalulekile ezilawula ukuhamba kwamandla kagesi. Phakathi kwezinhlobonhlobo zama-diode, ama-Zener diode nama-diode avamile agqamile, ngalinye linezici ezihlukile nezindlela zokusebenza. Nakuba bobabili benza izindima ezibalulekile kumasekethe kagesi, ukuqonda ukuhlukana kwabo kubalulekile ekukhetheni i-diode efanelekile yomsebenzi othile.
Ukungena kuma-Diode Ajwayelekile
Ama-diode avamile, awaziwa nangokuthi ama-PN junction diode, angamadivayisi avumela ukuthi amanje ageleze aye ohlangothini olulodwa (indlela eya phambili) kuyilapho eyivimbela ngakolunye uhlangothi (indlela ehlehlayo). Lesi sakhiwo esilungisayo sibenza babe izingxenye ezibalulekile ekuguquleni i-alternating current (AC) ukuze ibe eyamanje eqondile (DC).
Ukuhlola i-Zener Diodes
Ama-Zener diode, uhlobo olukhethekile lwe-diode, abelana ngesakhiwo esiyisisekelo kanye nezakhiwo zokulungisa zama-diode avamile kodwa abonisa imfanelo eyengeziwe ephawulekayo: ukuhlukana okulawulwayo. Lapho ingaphansi kwe-voltage echema ehlehlayo eyedlula i-voltage yawo ehlukanisiwe eshiwo, ama-diode e-Zener aphuka, anikeze amandla amanje ukuthi ageleze aye emuva. Lesi simo esilawulwayo sokuhlukaniswa sakha isisekelo sokusebenza kwazo okuhlukile.
Ukwembula Umehluko Oyinhloko
Umehluko ocacile phakathi kwama-Zener diode nama-diode ajwayelekile usekuziphatheni kwawo okuwohlokayo:
I-Breakdown Mechanism: Ama-diode avamile abonisa ukuwohloka kwe-avalanche, inqubo engalawuleki futhi engase ibe yingozi. Ngakolunye uhlangothi, ama-diode e-Zener abhekana nokuqhekeka kwe-Zener, isenzakalo esilawulwayo nesibikezelwayo sokuphuka.
I-Breakdown Voltage: Ama-diode avamile anobubanzi obuhlukahlukene bamandla okuqhekeka, ngokuvamile ahluka ngokubekezelela ukukhiqiza. I-Zener diode, ngokuphambene, iziqhayisa ngamandla kagesi achazwe kahle futhi aqinisekisiwe, okuwenza alungele ukusetshenziswa kokulawulwa kwamandla kagesi.
Izinhlelo zokusebenza: Ama-diode avamile ngokuyinhloko asebenza njengezilungisi, eziguqula i-AC ibe yi-DC. Ama-Zener diode ahamba phambili ekulawulweni kwe-voltage, ukuvikela i-overvoltage, i-voltage clamping, kanye nokubunjwa kwe-waveform.
Ukukhetha Diode Right
Ukukhetha phakathi kwe-Zener diode kanye ne-diode evamile kuncike ekusetshenzisweni okuqondile:
Ukuze kulungiswe: Ama-diode ajwayelekile ayinketho ekhethwayo yokuguqula i-AC ibe yi-DC.
Ngokulawulwa kwamandla kagesi: I-Zener diode iyinketho efanelekile yokugcina i-voltage ezinzile kuwo wonke umthwalo.
Ukuze kuvikelwe u-overvoltage: I-Zener diode ivikela izingxenye ezizwelayo ngokuvala i-voltage eyeqile ukuze ifike phansi ngesikhathi sokushwibeka noma ama-spikes.
Ngokucindezela i-voltage: I-Zener diode ingakhawulela amazinga kagesi aphezulu noma amancane kusekethe, ivimbele ukuhlanekezelwa kwesignali.
Ngokwakheka kwe-waveform: I-Zener diode ingalolonga amagagasi ngokusika noma ngokulungisa amasiginali we-AC.
Isiphetho
Ama-Zener diode nama-diode avamile, ngenkathi abelana ngesisekelo esifanayo, ayahlukana ekuziphatheni kwawo okuwohlokayo nasekusetshenzisweni kwawo. Ama-Zener diode, ane-voltage ehlukanisiwe echazwe kahle kanye nekhono lokulawula i-voltage, akhanya ezinhlelweni ezifuna ukuzinza nokuvikelwa. Ama-diode avamile, anekhono lawo lokulungisa, ahamba phambili ekuguquleni i-AC ibe yi-DC. Ukuqonda lokhu kwehluka kunika amandla abathanda i-elekthronikhi ukuthi benze izinqumo ezinolwazi lapho bekhetha i-diode efanelekile yamaphrojekthi abo.
