| 32CTQ...PbF Vishay High Power Products Schottky Rectifier, 2 x 15 A FEATURES Base 2 common cathode * 150 C TJ operation * Low forward voltage drop * High frequency operation * High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Pb-free Available RoHS* COMPLIANT Anode TO-220AB Anode 2 1 Common 3 cathode * Guard ring for enhanced ruggedness and long term reliability * Lead (Pb)-free ("PbF" suffix) * Designed and qualified for industrial level DESCRIPTION PRODUCT SUMMARY IF(AV) VR 2 x 15 A 25/30 V The 32CTQ...PbF Schottky rectifier series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 150 C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection.
