| Preliminary Data Sheet PD-20203 12/01 MBR0540 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 40 6.0 0.42 - 65 to 150 Case Styles Device Marking: IR540 K J L B A SOLDERING PAD 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 2 0.91 mm 0.036" 1.22 mm 0.048" 2.36 mm 0.093" www.irf.com H C 1 4.19 mm 0.165" (A) 1 2 (K) Outline SOD123 1 MBR0540 Preliminary Data Sheet PD-20203 12/01 Voltage Ratings Part number VR Max.
