| 40CTQ150 Vishay High Power Products Schottky Rectifier, 2 x 20 A FEATURES Base 2 common cathode * * * * * Anode TO-220AB Anode 2 1 Common 3 cathode 175 C TJ operation Center tap TO-220 package Very low forward voltage drop High frequency operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance * Guard ring for enhanced ruggedness and long term reliability * Designed and qualified for industrial level DESCRIPTION PRODUCT SUMMARY IF(AV) VR 2 x 20 A 150 V The 40CTQ... center tap Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection.
