Semiconductor Fuses
Littelfuse Semiconductor fuses are very fast acting fuses designed
specifically for the protection of diodes, thyristors, triacs, and other
solid-state power semiconductor devices. These fuses are used in
power electronic applications including variable speed drives, power
rectifiers, UPS systems, and DC power supplies. They can be used
wherever extremely fast acting, current-limiting fuses are needed to
provide superior protection against the potentially damaging effects of
short-circuit currents.
The extensive line of Littelfuse Semiconductor fuses includes the
traditional round body fuses, enhanced state-of-the-art round body
fuses, and North American style square body fuses. Available ratings
range from 150 to 1300 volts and up to 6000 amps.
Applications
Semiconductor fuses are designed specifically for supplementary
protection of semiconducting devices such as silicon controlled rectifiers
(SCR’s), diodes, thyristors, triacs, transistors, and similar solid-state
devices. These devices are used in power equipment including variable
speed drives, power rectifiers, UPS systems, DC power supplies, and in
a wide range of electronic equipment.
May be used wherever extremely fast acting, current-limiting fuses with
no time-delay are required.
