Los sistemas m\u00e1s eficaces combinan dos tecnolog\u00edas complementarias en un enfoque de dos etapas:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">La primera etapa es el <strong>GDT (Gas Discharge Tube)<\/strong>\u26a1 <br><br>Cuando un pico de voltaje de alta energ\u00eda golpea la l\u00ednea, el gas dentro del tubo se ioniza y crea un cortocircuito virtual \u2014 un efecto de \"crowbar\" \u2014 que desv\u00eda el exceso de energ\u00eda de forma segura hacia tierra. Una vez que la sobretensi\u00f3n cesa, el GDT regresa a su estado de alta impedancia, listo para el siguiente evento.<br><br><br><\/li>\n\n\n\n<li class=\"has-medium-font-size\">La segunda etapa es el <strong>TVS (Transient Voltage Suppressor)<\/strong>\ud83d\udee1\ufe0f<br><br>Los GDT son excelentes para manejar cargas de energ\u00eda masivas, pero ionizar el gas toma una fracci\u00f3n de segundo. Ese breve retardo es suficiente para que los picos m\u00e1s r\u00e1pidos e intensos pasen de largo. Los diodos TVS \u2014 componentes de estado s\u00f3lido \u2014 act\u00faan como una \"abrazadera de voltaje\" ultrarr\u00e1pida, interceptando esos transitorios iniciales antes de que el GDT siquiera
