Semiconductor Fuses
Littelfuse’s comprehensive range of semiconductor fuses are designed for protection of power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFETs and other solid state devices that are typically designed in to power conversion and power conditioning equipment.
Littelfuse’s semiconductor fuses are often used in variable frequency drives, inverters, UPS, rectifiers and soft-starters and offer enormous benefits.
