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.

Special Purpose Fuses
LA60X Semiconductor Fuses
600 VAC • Very Fast Acting • 700 – 2000 Amperes
Littelfuse LA60X semiconductor protection fuses are popular for the
protection of higher voltage heavy rectifiers such as traction rectifiers.
They can carry long sustained overloads common with heavy-duty
apparatus. The compact “hockey puck” design provides high power
protection in a small space.
Features
Lowest I2t minimizes damage to protected components on
•
short- circuit.
•
Controlled arc voltage reduces stress to circuit components during
fuse clearing.
Applications
Protection of heavy traction and electrochemical as well as rectifiers and
other heavy-duty equipment.

Special Purpose Fuses
LA100P Semiconductor Fuses
1000 VAC • Very Fast Acting • 15 – 1000 Amperes
Littelfuse LA100P semiconductor protection fuses are rated 1000V,
extending the range of protection for UPS systems, AC and DC drives,
reduced voltage motor starters and similar applications where lower I2t
and superior reliability are needed. With ratings from 15-1000 amperes,
a wide range of high voltage applications can be served.
Features
Low I2t minimizes damage to protected components on short-circuit.
Controlled arc voltage reduces stress to circuit components during
fuse clearing.
•
•
Applications
Protection of UPS systems, AC/DC drives, reduced voltage motor
starters and other 1000V or less semiconductor devices.

Special Purpose Fuses
Square Body Semiconductor Fuses
700/1300 VAC • Very Fast Acting • 40 – 2500 Amperes
Littelfuse North American style square body semiconductor fuses
provide maximum flexibility in equipment design and ultimate protection
for today’s power conversion equipment. Available in different body
sizes and multiple mounting styles, the broad range of ampere ratings
allows great flexibility in equipment design.
Engineered to provide state-of-the-art protection for SCR’s, diodes,
thyristors, GTO’s, and IGBT devices, Littelfuse square body fuses have
pure die-cut elements embedded in solidified sand to control arcing and
lower I2t. All fuses are also equipped with a blown fuse trip indicator.
Features
•
Choice of mounting styles provides a wide choice for equipment
design.
•
Broad range of ampere ratings in a given body size for design
flexibility.
Very low I2t minimizes damage to protected components.
Superior cycling ability for long, reliable life on high cyclic loading.
Extremely fast acting and current-limiting for improved protection to
equipment.
•
•
•
Applications
Ordering Information
Protection of rectifiers, inverters, DC drives, UPS systems, reduced
voltage motor starters, and other equipment in globally accepted
applications.
