Semiconductor Protection Fuses

Few of today's powered products don't rely on semiconductor technology to some degree. That means extending circuit protection to thyristors, triacs, diodes, and a host of other solid-state components. Mersen offers a vast, truly international line of semiconductor fuses to protect these sensitive components.

  • Multiple body sizes and terminals or blades combination

  • aR Class according to IEC 60269-4 and VDE 636-23

  • Very low I²t for improved semiconductor protection

  • Ultra fast acting

  • Current limiting

  • Superior cycling capability
