New D6X Combined Thermal Fuse/Resistor

The new SEFUSE D6X offers a new concept in thermal fuse technology.  By combining a thermal fuse element and resistor on a single substrate, NEC has created a fast-acting ultimate protection device for high power DC applications upto 12A/32VDC. 


The D6X works on two principles.  Firstly it operates like a conventional thermal fuse which will open when the local ambient temperature reaches the fuse’s operating temperature.  Secondly it responds to an over-current signal from a monitoring circuit which self-heats the resistor thus opening the adjacent fuse.


The D6X was designed to fit neatly in the space between adjacent MOSFETS thus improving response time and minimising board space required.
