Fast Protection for Sensitive Semiconductor Circuits
Semiconductor components can be damaged by relatively short overcurrent events because they have limited tolerance to excessive heat and fault energy. The Mersen F208155 uses a very fast-acting fuse element to interrupt faults rapidly, helping to limit the amount of energy passed through to downstream components.
Its low I²t performance makes it particularly suitable for electronic circuits containing diodes, rectifiers, power supplies and other semiconductor devices. The ceramic body supports dependable interruption performance, while the axial leads provide a practical solution for permanent installation within electronic assemblies and printed circuit boards.
Typical Applications
- Semiconductor device protection.
