El diodo Zener es un diodo de cromo1 que se ha construido para que funcione en las zonas de rupturas, recibe ese nombre por su inventor, el Dr. Clarence Melvin Zener. El diodo Zener es la parte esencial de los reguladores de tensión casi constantes con independencia de que se presenten grandes variaciones de la tensión de red, de la resistencia de carga y temperatura.
Si a un diodo Zener se le aplica una corriente eléctrica del ánodo al cátodo (polarización directa) toma las características de un diodo rectificador básico, pero si se le suministra corriente eléctrica de cátodo a ánodo (polarización inversa), el diodo solo dejara pasar un voltaje constante.
En conclusión: el diodo Zener debe ser polarizado al revés para que adopte su característica de regulador de tensión.
Su símbolo es como el de un diodo normal pero tiene dos terminales a los lados. Este diodo se comporta como un diodo convencional en condiciones de alta corriente porque cuando recibe demasiada corriente se quema.
