SEFUSE® D6 Battery Fuses

Product Description

Why are battery fuses needed?

Safety is the top priority for electronic devices, battery-powered tools, and vehicles. This has led to increased demand for highly reliable battery fuses. These components are designed to protect Li-ion batteries from potentially damaging and dangerous overcurrent and overcharging circumstances. At the same time, due to space limitations, the battery fuses must be extremely small – typically surface-mount types.

SCHOTT SEFUSE D6 battery fuses offer reliable overcurrent and overcharging protection for Li-ion batteries.


 SEFUSE D6 battery fuses offer the following advantages:
  • Suitable for high currents and compatible with up to 14 cells
  • Many variations available with different current and package sizes
  • Extremely thin and compact surface mount designs
  • RoHS Compliant 
  • Antimony-free
  • Halogen-free


D6 battery fuses are used for battery packs in:

High-current applications
  • Rechargeable power / garden tools
  • Cordless and robotic vacuum cleaners
  • E-bikes and E-motorcycles
  • Energy Storage Systems
Devices requiring miniaturized designs
  • Notebooks
  • Smartphones
  • Tablet PCs

Technical Details

How it works

SCHOTT SEFUSE® battery fuses offer comprehensive protection for electronic devices. The design and functionality protects Li-ion batteries from potentially damaging and dangerous overcurrent and overcharging circumstances.

In case overcurrent occurs while using the device, the fuse element will open and cut off the circuit. In case of overcharging, FET is activated and the heater element disables the fuse element, resulting in the circuit being cut off.
