ISL9R460PF2
4A, 600V Stealth鈩?Diode
General Description
The ISL9R460PF2 is a Stealth鈩?diode optimized for low
loss performance in high frequency hard switched
applications. The Stealth鈩?family exhibits low reverse
recovery current (I
RRM
) 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
RRM
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鈩?diode with
an SMPS IGBT to provide the most efficient and highest
power density design at lower cost.
Formerly developmental type TA49408.
