SMS05 through SMS24 TVS Diode Array For ESD and Latch-Up Protection PROTECTION PRODUCTS Features Description The SMS series of TVS arrays are designed to protect Transient protection for data lines to sensitive electronics from damage or latch-up due to IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) ESD and other voltage-induced transient events. Each IEC 61000-4-4 (EFT) 40A (5/50ns) device will protect up to four lines. They are available IEC 61000-4-5 (Lightning) 24A (8/20 s) with operating voltages of 5V, 12V, 15V and 24V. They Small package for use in portable electronics are unidirectional devices and may be used on lines Protects four I/O lines where the signal polarities are above ground. Working voltages: 5V, 12V, 15V and 24V TVS diodes are solid-state devices designed specifically Low leakage current for transient suppression. They feature large cross- Low operating and clamping voltages sectional area junctions for conducting high transient Solid-state silicon avalanche technology currents. They offer desirable characteristics for board level protection including fast response time, low Mechanical Characteristics operating and clamping voltage and no device degrada- EIAJ SOT23-6L package tion. Pb-Free, Halogen Free, RoHS/WEEE Compliant The SMS series devices may be used to meet the Lead Finish: Matte Sn immunity requirements of IEC 61000-4-2, level 4. The Molding compound flammability rating: UL 94V-0 low cost SOT23-6L package makes them ideal for use Marking : Marking code in portable electronics such as cell phones, PDAs, and Packaging : Tape and Reel notebook computers.
