| 12TQ...PbF Series Vishay High Power Products Schottky Rectifier, 15 A FEATURES Base cathode 2 * 150 C TJ operation * Very 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 TO-220AC 1 Cathode 3 Anode * 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 15 A 35 to 45 V The 12TQ...PbF 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, freewheeling diodes, and reverse battery protection.
