PD -94015 35CGQ100 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35 Amp, 100V Major Ratings and Characteristics Characteristics Description/Features 35CGQ100 Units IF(AV) 35 A VRRM (Per Leg) 100 V IFSM @ tp = 8.3ms half-sine (Per Leg) 150 A 0.99 V VF @ 35Apk, TJ =125°C (Per Leg) TJ, Tstg Operating and storage -55 to 150 The 35CGQ100 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hirel 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 Center Tap 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 ) 17.40 ( .685 ) 16.89 ( .665 ) 31.40 ( 1.235 ) 30.39 ( 1.199 ) 6.60 ( .260 ) 6.32 ( .249 ) 1 2 -B1.27 ( .050 ) 1.02 ( .040 ) 13.84 ( .545 ) 13.59 ( .535 ) LEGE ND 1 - CO LL 2 - E MIT 3 - GA TE 3 -C- 3X 3.81 ( .150 ) 2X 1.14 ( .045 ) 0.89 ( .035 ) .50 ( .020 ) .25 ( .010 ) 3.81 ( .150 ) M C A M B M C 1 2 3 ANODE COMMONANODE CATHODE IR Case Style TO-254AA www.irf.com 1 11/15/00 35CGQ100 Voltage Ratings Part number VR 35CGQ100 Max.
