PD - 93860A SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 10YQ045 10 Amp, 45V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM @ tp = 8.3ms half-sine 110 VF @ 10Apk, TJ =125°C 0.70 A V 10YQ045 10 45 Units A V Description/Features The 10YQ045 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic isolated TO-257AA 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 levels. Hermetically Sealed Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight • Glass Eyelets • • • • TJ,Tstg Operating and storage -55 to 150 °C CASE STYLE CATHODE OPEN ANODE IR Case Style TO-257AA www.irf.com 1 01/26/01 10YQ045 Voltage Ratings Part number VR Max.
