SDB310WMU

SDB310WMU SCHOTTKY BARRIER DIODE General Purpose Schottky Barrier Diode 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 SOT-323 Applications  General purpose and high speed switching  Protection circuit and voltage clamping Ordering Information Part Number Marking Code Package Packaging SDB310WMU DB3 □ SOT-323 Tape & Reel Marking Information DB3 □ DB3 = Specific Device Code □ = Year & Week Code Marking Pinning Information Pin 1 2 3 Description Anode (Diode 1) Cathode (Diode 2) Cathode (Diode 1), Anode (Diode 2) KSD-D5D017-001 www.auk.co.kr 1 of 5 Simplified Outline Graphic Symbol Rev. date: 25-AUG-10 SDB310WMU Absolute Maximum Ratings (Tamb=25℃, Unless otherwise specified) Characteristic Peak reverse voltage DC reverse voltage Repetitive peak forward current Forward current Non-repetitive peak forward surge current(t=10ms) Power dissipation 1) Symbol VRM VR IFRM IF IFSM PD Ratings 40 30 0.5 0.2 2 150 Unit V V A A A mW 1) Device mounted on FR-4 board with recommended pad layout.
