Product Brief CoolMOS™ in TO-247 4pin package A New Innovative Package Using Kelvin Source Concept Infineon Technologies introduces the new TO247 4pin package in conjunction with the latest CoolMOS™ technologies of 600 V C7, 650 V C7 and 600 V P6. With new generations of power switches becoming faster and faster, the effect of the parasitic elements of package and board limit more and more the overall system performance. In many applications the switching losses are significantly increased by the negative feedback caused by the parasitic inductance in the source lead of the power switch. An effective measure to overcome this problem is to provide an additional connection to the source (Kelvin connection), that is used as a reference potential for the gate driving voltage, thereby eliminating the effect of voltage drops over the source inductance. The achievable efficiency improvement, resulting from faster switching transients, can in fact be significant.
