Yintoni isakhiwo se-thyristor?

The kumnya ineepali ezintathu-anode (A), i-cathode (C) kunye nepali yokulawula (G). I-die yisakhiwo esine-four-layer eyenziwe ngumqhubi we-P kunye nomqhubi we-N. Zintathu iindibano zePN zizonke. Yahluke kakhulu kwisakhiwo ukusuka kwi-silicon rectifier diode ene-PN junction enye kuphela. Isakhiwo esine-four ye-thyristor kunye nokuqaliswa kwe-electrode yokulawula yabeka isiseko seempawu zayo ezibalaseleyo zokulawula “ukulawula okukhulu ngamancinci”. Ekusetyenzisweni kwe-thyristor, nje ngokuba i-current encinci okanye i-voltage yongezwa kwi-electrode yokulawula, i-anode enkulu yangoku okanye i-voltage inokulawulwa. Okwangoku, amacandelo e-SCR anomthamo wangoku wamakhulu aliqela e-ampere okanye amawaka e-ampere anokwenziwa. Ngokuqhelekileyo, ii-SCRs ezingaphantsi kwe-5 amperes zibizwa ngokuba yi-low-power SCRs, kwaye i-SCRs ngaphezu kwe-50 amperes ibizwa ngokuba yi-high-power SCRs.
