| ISL9K18120G3 May 2002 ISL9K18120G3 18A, 1200V StealthTM Dual Diode General Description The ISL9K18120G3 is a StealthTM dual diode optimized for low loss performance in high frequency hard switched applications. The StealthTM family exhibits low reverse recovery current (IRM(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 IRM(REC) and short ta 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 StealthTM diode with a 1200V NPT IGBT to provide the most efficient and highest power density design at lower cost. Formerly developmental type TA49414.
