| PD-2.320 rev. B 06/99 MBR2045CT MBRB2045CT MBR2045CT-1 SCHOTTKY RECTIFIER Description/Features Units A This center tap Schottky rectifier 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, free-wheeling diodes, and reverse battery protection. 150 C TJ operation Center tap TO-220 and D2Pak packages Low forward voltage drop High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance High frequency operation Guard ring for enhanced ruggedness and long term reliability 20 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform (Per Device) IFRM @ TC = 135C (Per Leg) VRRM IFSM @ tp = 5 s sine VF TJ @ 10 Apk, TJ = 125C range 20 35/45 1060 0.57 - 65 to 150 A V A V C Values 20 Case Styles MBR2035CT MBR2045CT MBRB2035CT MBRB2045CT MBR2035CT-1 MBR2045CT-1 TO-220 D2PAK TO-262 www.irf.com 1 MBR2045CT, MBRB2045CT, MBR2045CT-1 PD-2.320 rev.
