| Bulletin PD-20643 rev. A 02/02 MBRA120TR SCHOTTKY RECTIFIER 1.0 Amp SMA Major Ratings and Characteristics Characteristics IFAV VRRM IFSM VF TJ @ tp = 5 s sine @1.0Apk,TJ=125C range Rect. Waveform Description/ Features The MBRA120TR 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 MBRA120TR Units 1.0 20 310 0.34 - 65 to 150 A V A V C Device Marking: IR12A CATHODE ANODE 1.40 (.055) 1.60 (.062) 2.50 (.098) 2.90 (.114) 1 2 4.00 (.157) 4.60 (.181) .152 (.006) .305 (.012) 2.00 (.078) 2.44 (.096) 0.76 (.030) 1.52 (.060) .103 (.004) .203 (.008) 4.80 (.188) 5.28 (.208) 1 POLARITY 2 PART NUMBER 1.47 MIN.
