| MBR4045WT Vishay High Power Products Schottky Rectifier, 2 x 20 A Base common cathode 2 FEATURES * 150 C TJ operation * Center tap TO-247 package * Very low forward voltage drop * High frequency operation * High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance TO-247AC 1 3 Anode Anode 2 1 2 Common cathode * Guard ring for enhanced ruggedness and long term reliability * Designed and qualified for industrial level DESCRIPTION PRODUCT SUMMARY IF(AV) VR IRM 2 x 20 A 45 V 85 mA at 125 C The MBR4045WT 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 150 C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection.
