FF1N30HS60DD
30A, 600V Stealth™ Diode
General Description
The FF1N30HS60DD is a Stealth™ diode optimized for low
loss performance in high frequency hard switched applications.
The Stealth™ family exhibits low reverse recovery current
(I
RM(REC)
) and exceptionally soft recovery under typical
operating conditions.
This device is intended for use as a free wheeling or boost
diode in power supplies and other power switching
applications. The low I
RM(REC)
and short t
a
phase reduce loss
in switching transistors. The soft recovery minimizes ringing,
expanding the range of conditions under which the diode may
be operated without the use of additional snubber circuitry.
Consider using the Stealth™ diode with an SMPS IGBT to
provide the most efficient and highest power density design at
lower cost.
Formerly developmental type TA49411
