SEFUSE D6SC Ultra Thin SMD Logic Fuse

The SEFUSE D6SC series of battery logic fuses provides valuable overcharge and over-current protection of Li-ion battery packs.  Unlike ordinary current fuses, it offers two levels of protection.

The D6SC carries the full battery operating current under normal conditions.  If the battery is short-circuited, the fuse simply blows due to the excessive currents.  If the battery is overcharged, then the D6SC’s built-in heater is triggered by the FET linked to the battery’s secondary protection IC.  This heater then blows the D6SC fuse and thus protects the Li-ion battery.

Ideal for protecting smartphones, tablets, notebooks and cordless power tool batteries.

New D6SA & D6SE versions offer protection up to 45A (and higher) for e-bike and e-vehicle applications.  Call on 01606 871680 to discuss latest options available
