Fairchild Semiconductor’s Dual Cool™ package improves power density and performance in DC-DC power applications

Article Type: New products From: Microelectronics International, Volume 30, Issue 2

Designers of DC-DC conversion applications are challenged with improving power density while saving board space and reducing thermal resistance. Fairchild Semiconductor’s (NYSE: FCS) new mid-voltage PowerTrench^® MOSFETs with Dual Cool™ packaging technology are well suited to help with these design challenges.

Fairchild has expanded and improved its Dual Cool packaging portfolio, an industry-standard pin-out package with top-side cooling, to include a 40-100 V mid-voltage series. Silicon technology advancements, paired with the Dual Cool technology, provide excellent switching performance as well as low junction-to-ambient thermal resistance that is four times less than the standard over-molded 5 mm×6 mm MLP.

Devices included in the mid-voltage series include the 40 V FDMS8320LDC, 60 V FDMS86500DC, 80 V FDMS86300DC and the 100 V FDMS86101DC. These devices are synchronous rectifying MOSFETs that are suitable for use in DC-DC converters, telecom secondary-side rectification and high-end server/workstation applications.
