PD -94014A 35SGQ030 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35 Amp, 30V Major Ratings and Characteristics Characteristics Description/Features 35SGQ030 Units IF(AV) 35 A VRRM 30 V 300 A 0.69 V IFSM @ tp = 8.3ms half-sine VF @ 35Apk, TJ =125°C TJ,Tstg Operating and storage -55 to 150 The 35SGQ030 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic 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 Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight °C .12 ( .005 ) CASE STYLE 13.84 ( .545 ) 13.59 ( .535 ) 3.78 ( .149 ) 3.53 ( .139 ) -A - 20.32 ( .800 ) 20.07 ( .790 ) 1 2 13.84 ( .545 ) 13.59 ( .535 ) 3 -C - 3X 3.81 ( .150 ) 2X -B 1.27 ( .050 ) 1.02 ( .040 ) 17.40 ( .685 ) 16.89 ( .665 ) 31.40 ( 1.235 ) 30.39 ( 1.199 ) 6.60 ( .260 ) 6.32 ( .249 ) 1.14 ( .045 ) 0.89 ( .035 ) .50 ( .020 ) .25 ( .010 ) LEG EN D 1 - CO LL 2 - E MIT 3 - GA TE 3.81 ( .150 ) M C A M B M C CATHODE OPEN ANODE IR Case Style TO-254AA www.irf.com 1 08/14/01 35SGQ030 Voltage Ratings Part number VR 35SGQ030 Max.
