| Preliminary Data Sheet PD-20226 01/02 MBR0520 SCHOTTKY DIODE 0.5 Amp SOD123 Major Ratings and Characteristics Characteristics IF(AV) DC VRRM IFSM VF TJ @ tp= 10 ms sine @0.5Apk, TJ=100C range Description/ Features Units A V A V C This Schottky diode is ideally suited for low voltage, high frequency operation, as freewheeling and polarity protection. Small size of the package allows proper use in application where compact size is critical, fitting also the GSM and PCMCIA requirement. Surface mountable Very low forward voltage drop Extremely fast switching Negligible switching losses Guard ring for enhanced ruggedness and long term reliability Value 0.5 20 6.5 0.36 - 65 to 150 Case Styles Device Marking: IR520 K J L B A 2 DIM A B C H J K L M Millimeters Min 0.55 1.40 3.55 2.55 0.95 8 Max 0.70 1.70 3.85 2.85 0.10 1.35 1.35 0.15 Inches Min 0.022 0.055 0.140 0.100 0.037 Max 0.028 0.067 0.152 0.112 0.004 0.053 0.053 0.006 8C SOLDERING PAD 0.91 mm 0.036" 1.22 mm 0.048" 2.36 mm 0.093" H 1 4.19 mm 0.165" C 1 2 Outline SOD123 1 MBR0520 Preliminary Data Sheet PD-20226 01/02 Voltage Ratings Part number VR Max.
