SDB3101 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 SOT-23 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 Ordering Information Part Number Marking Code Package Packaging SDB3101 DB1 □ SOT-23 Tape & Reel Marking Information DB1 □ DB1 = Specific Device Code □ = Year & Week Code Marking Pinning Information Pin Description 1 Anode 2 Not Connected 3 Cathode Rev. date: 25-AUG-10 Simplified Outline KSD-D5C039-001 Graphic Symbol www.auk.co.kr 1 of 5 SDB3101 Absolute Maximum Ratings (Tamb=25℃, Unless otherwise specified) Characteristic Symbol Ratings Unit Peak reverse voltage VRM 40 V DC reverse voltage VR 30 V Repetitive peak forward current IFRM 0.5 A IF 0.2 A IFSM 2 A PD 150 mW Symbol Ratings Unit Rth(j-a) 833 C/W Tj 150 C Tstg -55 ~ 150 C Forward current Non-repetitive peak forward surge current(t=10ms) Power dissipation 1) 1) Device mounted on FR-4 board with recommended pad layout.
