As the current flow increases, the particles inside the fuse will start moving fast. The slow motion of these particles are the ones keeping a smooth current flow across the fuse. When the particles are moving rapidly, it will oppose the current flow through them. Imagine a situation where a short circuit happens.

WebA variety of prior art fuses have been used in ICs. For example, one fuse structure is formed by the so-called "Zener zap" method. Such fuses operate in the "open" state by default, up to the Zener voltage; and are operated in the "closed" state by causing a very large current (typically >200 mA) to flow for a long period of time (typically >1 sec) through the fuse's … WebTypes of Fuses– Advantages and Disadvantages of Electric Fuse.
