Bussmann SF25H140 Semiconductor Fuse for Circuit Protection

Bussmann SF25H140 Semiconductor Fuse for Circuit Protection

The Bussmann SF25H140 is a semiconductor fuse built to help protect sensitive semiconductor devices and power electronic components from damaging overcurrent conditions. Unlike a general-purpose fuse, a semiconductor-class fuse like the SF25H140 is engineered specifically to coordinate with solid-state components such as diodes, thyristors, and rectifiers, where standard overcurrent protection is not sufficient to prevent device damage during a fault. Bussmann is a long-established name in circuit protection, and the SF25H140 reflects that focus on protecting demanding electrical and industrial power systems. Because semiconductor fuses are typically selected to match the specific voltage, current, and let-through requirements of the equipment they protect, exact ratings and dimensions for the SF25H140 should be confirmed before specifying it for a given application. Complete compliance and performance documentation for this fuse is available directly from the factory.
