Rev. date: 11-MAR-11 KSD-D5C072-000 www.auk.co.kr 1 of 5 SDB0740 SCHOTTKY BARRIER DIODE Schottky Barrier Rectifier General Description These Schottky barrier diodes are designed for high-speed switching applications, circuit protection, and voltage clamping. Extremely low forward voltage reduces conductions. Miniature surface mount package is excellent for hand-held and portable applications where space is limited. Features and Benefits Low forward drop voltage and low leakage current Very low switching time Full lead (Pb)-free device and RoHS compliant device Available in “Green” device
Applications
General purpose and high speed switching Protection circuit and voltage clamping
