New entry into competitive power semiconductor market offers 650-V-rated models in a wide variety of package configurations

Semiconductor introduced the +FET line of 650-V-rated superjunction
. +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 new
+FET product rollout includes over 50 devices with 13 different RDS(ON)
ratings ranging from 1,000 mΩ to 32 mΩ. Packages types include: traditional
thru-hole (TO-220/TO-220FP), surface-mount (DPAK/D2PAK), and advanced surface-mount
(5 x 6/8 x 8) devices. For all package sizes and ratings, D3 Semiconductor’s
+FET devices exhibit a Qg RDS(ON) Figure of Merit (FOM)
that is among the highest available.

The high efficiency of the new +FET MOSFETs, gained
by lowering switching and conduction losses, helps to simplify thermal
management. The devices’ smooth switching behavior reduces switching noise and
drives faster design cycles by lowering the need for snubber circuits. Their
advantage of higher ampacity per package type improves power supply density, which, in turn, enables the use of advanced surface-mount packages in higher-power

“In addition to the
+FET’s excellent performance and reliability, our roadmap is changing the DNA
of power devices by infusing mixed-signal functions into high-voltage switching
devices,” said Tom
Harrington, D3 Semi’s Chief Technology Officer.


“The initial product lineup
of +FET devices are high-performance superjunction MOSFETs that offer socket-for-socket
alternatives to competitive parts,” said Marty Brown,
Senior Consultant for D3. “Their capabilities place
more control into the designer’s hands so that systems can be optimized for
power density while reducing design cycle time. Extensive benchmarking of these
products is already proving their world-class, competitive performance.”
