ULTRA QUICK - SEMICONDUCTOR PROTECTION: ETI fuse-links for semiconductor protection ULTRA QUICK present an optimal solution for protection of power semiconductors, such as diodes, thyristors and other power semiconductors in DC and AC power applications such as AC/DC, DC/AC, DC/DC converters and frequency converters. ETI fuse-links elements for semiconductor protection comply with IEC 60269 and VDE 0636 standards.
Through the past few years, the transient voltage surge suppresion (TVSS) industry has grown to one
of the fastest-growing segments among power protection products. Newness from ETI is series of
fuses named SRF (Surge Rated Fuses), intended for the protection of TVSS products. The SRF Series has
been designed to survive 8/20 us lighting surge pulses without operating, allowing the TVSS system to
react to the surge. All surge fuses have 8/20 us ratings, not a continuous current rating.
These fuses are intended to be installed in series with the TVSS devices and do not normally carry
current, except for the periodic random surges caused by TVSS breakdown during normal operation.
Under AC short circuit conditions these SRF surge suppression fuses have extremely high capability for
