Semi Conductor Fuse - an overview

Semiconductor fuses serve to product semiconductor components such as diodes and triacs. These fuses are made specially to act quickly within milliseconds to isolate the electronic component.  

Semiconductor fuses are made of silver strips.  The cross section of these strips determines the fuse limits.  A number of strips may be connected in parallel to provide the desired fuse rating. The strips are enclosed in a tubing containing quartz which serves to quench the arc. 

Semiconductor fuses are designed to act at overloads of 5 to six times the rated capacity.   These fuses are available at MV ratings with a capacity of several thousand amperes.
