ISL9R18120G2 / ISL9R18120P2 / ISL9R18120S3S
18A, 1200V Stealth Diode
General Description
The ISL9R18120G2, ISL9R18120P2 and ISL9R18120S3S are
Stealth diodes 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 a 1200V NPT IGBT to
provide the most efficient and highest power density design at
lower cost.
Formerly developmental type TA49414
