Bulletin PD-20226 rev. A 10/06 MBR0520 0.5 Amp SCHOTTKY DIODE IF(AV) = 0.5Amp VR = 20V 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.
