March 29, 2017

According to D3 Semiconductor, its latest +FET line of 650V-rated superjunction MOSFETs. +FET MOSFETs enable high-efficiency solutions for a range of hard-switched applications, including PFC boost and inverters used in telecom, enterprise computing, UPS and solar. The roll-out includes over 50 devices with 13 different RDS(ON) ratings ranging from 1000 mΩ to 32 mΩ. Packages types include: traditional thru-hole (TO-220/TO-220FP), surface-mount (DPAK/D2PAK) and advanced surface-mount (5×6/8×8) devices. For all package sizes and ratings, D3 Semiconductor's +FET devices exhibit a Qg RDS(ON) FOM (Figure of Merit) that is among the highest available. Pricing for a 650V/80mΩ +FET is $1.84 each/1,000.
