Abstract

La présente invention décrit un dispositif et matériau (12) pour circuits électroniques qui assure une protection contre les impulsions de surtension transitoires rapides (11). Le dispositif à électrodes (24) peut en outre être adapté pour assurer une division électrostatique. Des particules conductrices (22) sont dispersées uniformément dans une matrice ou un liant isolant (23) pour produire un matériau ayant des caractéristiques de résistance non linéaire. Les caractéristiques de résistance non linéaire du matériau sont déterminées par l'espacement des particules à l'intérieur du liant ainsi que par les propriétés électriques du liant isolant. En adaptant la séparation entre les particules conductrices, ce qui permet de réguler le tunnelage quantum-mécanique, on peut faire varier les propriétés électriques du matériau non linéaire à l'intérieur d'une plage de variation étendue.
