Tandem 600V HYPERFAST BOOST DIODE
The
TURBOSWITCH
"H"
is
an
ultra
high
performance diode composed of two 300V dice in
series. TURBOSWITCH "H" family drastically cuts
losses in the associated MOSFET when run at
high dI
F
/dt.
DESCRIPTION

CONDITIONS
s
DESIGNED FOR HIGH DI/DT OPERATION.
HYPERFAST
RECOVERY
CURRENT
TO
COMPETE WITH SIC DEVICES. ALLOWS
DOWNSIZING OF MOSFET AND HEATSINKS
s
INTERNAL CERAMIC INSULATED DEVICES
WITH EQUAL THERMAL CONDITIONS FOR
BOTH 300V DIODES
