PD -94229 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35SCGQ030 35 Amp, 30V Major Ratings and Characteristics Characteristics IF(AV) VRRM (Per Leg) IFSM @ tp = 8.3ms half-sine (Per Leg) VF @ 17.5Apk, T J =125°C (Per Leg) 35SCGQ030 Units 35 30 150 A V A Description/Features The 35SCGQ030 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hirel environments. It is packaged in the hermeticly isolated TO-254AA package. The device's forward voltage drop and reverse leakage current are optimized for the lowest power loss and the highest circuit efficiency for typical high frequency switching power supplies and resonent power converters. Full MIL-PRF-19500 quality conformance testing is available on source control drawings to TX, TXV and S quality levels. • • • • • Hermetically Sealed Center Tap Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight 0.53 V TJ, Tstg Operating and storage -55 to 150 °C .12 ( .005 ) CASE STYLE 3.78 ( .149 ) 3.53 ( .139 ) -A- 13.84 ( .545 ) 13.59 ( .535 ) 6.60 ( .260 ) 6.32 ( .249 ) -B1.27 ( .050 ) 1.02 ( .040 ) 17.40 ( .685 ) 16.89 ( .665 ) 31.40 ( 1.235 ) 30.39 ( 1.199 ) 1 2 3 20.32 ( .800 ) 20.07 ( .790 ) 13.84 ( .545 ) 13.59 ( .535 ) -C- L EGE ND 1 - CO L L 2 - E MIT 3 - G A TE 3X 3.81 ( .150 ) 2X 1.14 ( .045 ) 0.89 ( .035 ) .50 ( .020 ) .25 ( .010 ) M C AM B MC 3.81 ( .150 ) 1 2 3 ANODE COMMONANODE CATHODE IR Case Style TO-254AA www.irf.com 1 06/19/01 35SCGQ030 Voltage Ratings Part number VR Max.
