## STEALTH Diode ## **18 A, 1200 V** ## ISL9R18120G2, ISL9R18120S3S ## **Description** The ISL9R18120G2, ISL9R18120S3S is a STEALTH diode optimized for low loss performance in high frequency hard switched applications. The STEALTH family exhibits low reverse recovery current (IRR) 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 IRR 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 STEALTH diode with an SMPS IGBT to provide the most efficient and highest power density design at lower cost. ## **Features** - Stealth Recovery trr = 300 ns (@ IF = 18 A) - Max Forward Voltage, VF = 3.3 V (@ TC = 25°C) - 1200 V Reverse Voltage and High Reliability - Avalanche Energy Rated - These Devices are Pb−Free and are RoHS Compliant ## **Applications** ## **www.onsemi.com** **==> picture [172 x 188] intentionally omitted <==** **----- Start of picture text -----**<br> CATHODE ANODE<br>(BOTTOM SIDE CATHODE<br>METAL)<br>$Y&Z&3&K<br>R18120G2<br>TO−247−2LD<br>0 CASE 340CL<br>CATHODE<br>(FLANGE)<br>$Y&Z&3&K<br>R18120S3S<br>N/C<br>ANODE<br>D [2] PAK−3 (TO−263, 3−LEAD) a s<br>CASE 418AJ<br>**----- End of picture text -----**<br> ## **MARKING DIAGRAM** - Hard Switched PFC Boost Diode - UPS Free Wheeling Diode - Motor Drive FWD - SMPS FWD - Snubber Diode $Y = ON Semiconductor Logo &Z = Assembly Plant Code &3 = Numeric Date Code &K = Lot Code R18120G2, R18120S3S = Specific Device Code ## **SYMBOL** K A ## **ORDERING INFORMATION** See detailed ordering and shipping information on page 2 of this data sheet.
