50HQ Datasheet | International Rectifier

cription/ Features Units A The 50HQ Schottky rectifier series has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 150° C TJ operation Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Hermetic packaging 50HQ...
