Los semiconductores son componentes electrónicos extremadamente sensibles a las sobrecargas y los cortocircuitos, por lo que no pueden protegerse mediante fusibles convencionales. Por ello existen fusibles ultrarrápidos específicos para este fin, cuyos principales requisitos son la fusión rápida, unos bajos valores de energía (I2t), reducidos valores de tensión de arco.
Aplicaciones típicas: protección de semiconductores (diodos, tiristores, triacs, etc) en rectificadores de potencia, UPS, convertidores, variadores de velocidad de motores (AC y DC), arrancadores suaves, relés de estado sólido, inversores para centrales fotovoltaicas, inversores para soldadura y en general cualquier aplicación donde se precise proteger componentes semiconductores.
Los elementos de fusión están especialmente diseñados y realizados en plata lo que proporciona bajos valores de I2t y tensiones de arco reducidas, así como un buen comportamiento al envejecimiento.
