What are semiconductor fuses?

semiconductor fuses are current protective devices that disconnect the circuit or device when the predefined current limit is reached. They are a very popular replacement for alternating current fuses (AC) and direct current (DC) in many areas. Any excess currents cause the perimeter to open the semiconductor fuse and prevent damage to the circuit. Semiconductor fuses are usually used to protect semiconductors, where they protect electronic components such as diodes, transistors and integrated circuits (ICS). When the fuse evaluation was exceeded, the fuse conductor was fallen and cut out of the protective circuit and the fuse was replaced. This mechanism is still used for uncritical applications. A circuit breaker with 30 amper (a) can be designed to trip or break the perimeter into more than 30 A. In most cases, the circuit breaker can be reset by overturning the cradle switch to the "ON" position. If an attempt to reset the circuit breaker with a circuit that still has current overload, ODWater will not energy. As a result, the circuit breaker is very popular for all places, including houses.

semiconductor fuses are smaller than glass fuses that have a glass tube with connecting covers at each end. The glass tube is about a thumb (2.54 cm) long with a visible fuse material that facilitates the inspection if the glass fuse still works. The conductive material on the glass fuse can be thinner than the spring of human hair. Like glass fuses, semiconductor fuses can be mounted on plates with circuits (PCB), or there may be fuses inside special brackets. The semiconductor fuses could be less than five times the equivalent shm.

generally have semiconductor fuses compared to fuses and circuit breakers with circuits, as the rapid response time saves electronic and electrical equipment before damage. Older fuses are also evaluated on the basis of time fromEzvy. After reaching the current limits, fast blocking fuses are rapidly open, while slowly blowing fuses are used to tolerate momentary excessive flows, for example during the start -ups of the engine and cold starts of electronic equipment. The start of an electric motor includes temporary initial currents that can be about 30% more than a stable running current, and the electrical resistance of most devices decreases with temperature drops. Depending on the local climate, some electronic devices have a preliminary preliminary sequence for managing potential overweights on the start-up.
