Fast fuse is a kind of fuse. Fast fuse is mainly used for short-circuit protection of semiconductor rectifier or rectifier. The overload ability of semiconductor components is very low. Only in a very short period of time to withstand a large overload current, so short circuit protection is required to have the ability to fuse quickly. The structure of the fast fuse is basically the same as that of a packed closed fuse, but the melt material and the shape of the fuse are different. It is a variable section melt with a V shaped deep groove made of silver.
In addition to having a certain shape of wire, the fuse of the fast fuse can also spot some kind of solder joint on it, in order to make the fuse break quickly in the case of overload.

The fast fuse is "fast" and also has high sensitivity. When the circuit current is overloaded, the fuse is rapidly heated, and the fuse is quickly disconnected under the action of the solder joint. The efficiency of the good fast fuse is quite high. It is mainly used to protect silicon controlled and some electronic power components.
