SMDA05 through SMDA24 Unidirectional TVS Array for Protection of Four Lines PPRROOTECTION PRTECTION PRODUCTODUCTSS Features Description The SMDAxx series of TVS arrays are designed to provide Transient protection for data lines to undirectional protection for sensitive electronics from IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) damage or latch-up due to ESD, lightning, and other IEC 61000-4-4 (EFT) 40A (5/50ns) voltage-induced transient events. Each device will IEC 61000-4-5 (Lightning) 12A (8/20s) protect four data or I/O lines. They are available with Undirectional protection operating voltages of 5V, 12V, 15V and 24V. Small SO-8 package Protects four I/O lines Working voltages: 5V, 12V, 15V and 24V TVS diodes are solid-state devices designed specifically for transient suppression. They offer desirable charac- Low leakage current teristics for board level protection including fast re- Low operating and clamping voltages sponse time, low operating and clamping voltage and no Solid-state silicon avalanche technology device degradation. The low profile SO-8 package allows Mechanical Characteristics the user to protect up to four independent lines with one package. The SMDAxx series is suitable protection for JEDEC SO-8 package sensitive semiconductors components such as micropro- Molding compound flammability rating: UL 94V-0 cessors, ASICs, transceivers, transducers, and CMOS Marking : Part number, date code, logo memory. Packaging : Tube or Tape and Reel per EIA 481 The SMDAxx series devices may be used to meet the Applications ESD immunity requirements of IEC 61000-4-2, level 4 for RS-232 data lines air and contact discharge.
