Special Purpose Fuses

Semiconductor Fuses

150 – 1300 VAC • Very Fast Acting • 1 – 6000 Amperes

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.
