Everything Else
Semiconductor fuses are specifically made for protecting fragile electronic devices such as diodes, IGBTs, SCRs and other types of power semiconductors from short circuits and overcurrent conditions. Semiconductor fuses operate much faster than standard fuses (usu. within microseconds), which minimizes thermal and electrical stress on sensitive devices. When the fault occurs semiconductor fuses interrupt the current before any excessive energy can accumulate to damage the crucial components thereby ensuring system stability and longevity. Their accurate operating characteristics can provide these valuable characteristics for high-speed circuits of variable frequency drives (VFD's), UPS, power supplies, industrial automation etc. Their cost-effective, rapid, reliable protection is an important part of limiting downtime and costly failure in electronic and power control systems.
