| 175BGQ045 Vishay High Power Products Schottky Rectifier, 175 A FEATURES * * * * * 150 C TJ operation High frequency operation Ultralow forward voltage drop RoHS COMPLIANT Continuous high current operation Guard ring for enhanced ruggedness and long term reliability * PowerTabTM package * Lead (Pb)-free plating Cathode Anode PowerTabTM DESCRIPTION PRODUCT SUMMARY IF(AV) VF at 175 A at 25 C IR at 125 C VR 175 A 0.75 V 640 mA 45 V The 175BGQ045 Schottky rectifier has been optimized for ultralow forward voltage drop specifically for low voltage output in high current AC/DC power supplies. The proprietary barrier technology allows for reliable operation up to 150 C junction temperature. Typical applications are in switching power supplies, converters, reverse battery protection, and redundant power subsystems.
