Bulletin PD-21132 rev. A 08/06 MBR0540PbF SCHOTTKY DIODE 0.5 Amp IF(AV) = 0.5Amp VR = 40V Description/ Features Major Ratings and Characteristics Characteristics 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.
