July 24, 2019, Princeton, New Jersey: UnitedSiC, a manufacturer of
silicon carbide (SiC) power semiconductors, has added two new TO220-3L
package options to its growing range of hard-switching UF3C FAST series
of 650V SiC FETs.
The new products offer RDS(on) values of 30mohms (UF3C065030T3S) (https://unitedsic.com/datasheets/DS_UF3C065030T3S.pdf) and 80mohms (UF3C065080T3S) (https://unitedsic.com/datasheets/DS_UF3C065080T3S.pdf).
The three-leaded, industry-standard TO220-3L package features enhanced
thermal characteristics made possible by a sintered-silver packaging
technology developed by UnitedSiC.
The new devices will appeal to designers who are seeking a more
powerful performance in a 3-lead TO220 package option for applications
such as EV charging, PV inverters, switch mode power supplies, power
factor correction modules, motor drives and induction heating.
Both new SiC FET products are based on a unique UnitedSiC ‘cascode’
circuit configuration, in which a normally-on SiC JFET is co-packaged
with a Si MOSFET to produce a normally-off SiC FET device. The device’s
standard gate-drive characteristics allows a true “drop-in replacement”
to Si IGBTs, Si FETs, SiC MOSFETs or Si superjunction devices on
existing designs in which designers can expect a performance increase
with lower conduction and switching losses, enhanced thermal properties
and integrated gate ESD protection.
In the case of new designs, the UnitedSiC FETs deliver increased
switching frequencies to gain substantial system benefits in both
efficiency and reduction in size, and cost of passive components, such
as magnetics and capacitors. The FAST Series devices offer not only
ultra-low gate charge, but also the best reverse recovery
characteristics of any device of similar ratings. These devices are
excellent for switching inductive loads when used with recommended
RC-snubbers, and any application requiring standard gate drive.
The UnitedSiC UF3C FAST SiC series, which now totals 14 devices, is
available in a range of TO247-3L, TO247-4L, TO220-3L and D2PAK7-3L
packages, with four 1200V and ten 650V options.
