  • Applications
  • Features
For supplementary protection of semiconducting devices such as silicon controlled rectifiers (SCR's), diodes, thyristors, triacs, transistors and similar solid state devices, power equipment including variable speed drives, power rectifiers, UPS systems, DC power supplies and in a wide range of electronic equipment, electrical and industrial applications
Reliable interruption of all overcurrents meets present and future system requirements
Extremely current limiting - low i2t and peak let-through currents meet most semiconductor requirements
Low watt losses - means less heating and power consumption in circuit
Controlled transient overvoltages - all circuits are subject to transient overvoltages during fault current interruption
These transient overvoltages (arc voltages) start when fuse links melt or circuit breaker contacts part and subside when circuit is interrupted
Semiconductors are very sensitive to overvoltages
Littelfuse® semiconductor fuse designs keep transient overvoltages to low levels and help reduce semiconductor failure
May be used wherever extremely fast acting, current limiting fuses with no time delay are required
