Our experienced research and development team works closely with our customers to create innovative solutions for the electronics market. One of our latest achievements, the NEC SCHOTT SEFUSE® D6 type, is a device that contains an electrical resistor which. In situations when the load becomes unsustainable, the electrical resistor would heat itself until the thermal element melts and interrupts the current.
The three D6 types, namely D6T, D6X, and D6WX devices, are integrated into the current circuit of a battery pack. The purpose is to interrupt the flow when overheating leads to dangerous levels. When the ambient temperature reaches a critical point, the thermal elements of these D6 devices would heat up in response to the rising temperature and melt the thermal elements to break an electric circuit.
The D6 type thermal cutoff offers the following advantages:
The D6 type is mainly used for battery packs that are embedded in notebook computers, tablet computers and power tools.
D6T, D6X and D6WX types
The D6 types are covered by a ceramic base and cap. Within this device, two leads are connected by a special flux-coated fusible alloy that acts as a thermal element. A third lead is also connected via an internal resistor which will produce heat if the load becomes unsustainable. In case of an abnormal temperature increase, either due to the external environment or to the heat generated by the internal resistor, the alloy would melt and interrupt the current.
Similar to the other D6 types, the D6S series contains a heater resistance that generates heat in response to an external signal. The excess heat melts the fuse element and cuts off the electrical circuit immediately. The space-saving thin design of D6S is ideal for surface mounting onto the protection circuit board of lithium batteries.
