The Relationship Between Pre-Arc and Post-Arc in Semiconductor Fuses

The Relationship Between Pre-Arc and Post-Arc in Semiconductor Fuses

During operation, the pre-arc and post-arc phases of semiconductor fuses The Relationship Between Pre-Arc and Post-Arc in Semiconductor Fusesare closely interrelated. The pre-arc phase refers to the stage where the fuse withstands overload current but does not melt. Factors such as current magnitude and duration during this phase determine the conditions of the subsequent post-arc phase. The post-arc phase involves the process of the fuse melting, generating an arc, and extinguishing. The energy accumulated during the pre-arc phase influences the characteristics and difficulty of arc extinction in the post-arc phase. Together, these two phases ensure the safety and stability of the circuit.
