| Bulletin PD-20591 rev. A 02/02 MBRS140TR SCHOTTKY RECTIFIER 1 Amp SMB Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @1.0 Apk, TJ=125C range Description/Features The MBRS140TR surface-mount Schottky rectifier has been designed for applications requiring low forward drop and very small foot prints on PC boards. Typical applications are in disk drives, switching power supplies, converters, free-wheeling diodes, battery charging, and reverse battery protection. Small foot print, surface mountable Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability MBRS140TR Units 1.0 40 380 0.53 - 55 to 150 A V A V C Device Marking: IR14 CATHODE ANODE 2.15 (.085) 1.80 (.071) 3.80 (.150) 3.30 (.130) 1 2 4.70 (.185) 4.10 (.161) 1 POLARITY 2 PART NUMBER 2.40 (.094) 1.90 (.075) 1.30 (.051) 0.76 (.030) 0.30 (.012) 0.15 (.006) 5.60 (.220) 5.00 (.197) 2.5 TYP.
