SMDA05 thru 00 Watt Surface Mount TVS Array SMDA36 TEL: 805-498-2111 FAX: 805-498-3804 DESCRIPTION FEATURES: The SMDA series of transient voltage suppressors are @ 300 watts Peak Pulse Power (tp = 8 x 20 ps) designed to protect components which are connected to Transient protection for data, signal, and Vcc bus data and transmission lines from voltage surges caused to IEC 1000-4-2 (ESD) & IEC 1000-4-4 (EFT) by electrostatic discharge (ESD), electrical fast @ Protects up to four bidirectional or four transients (EFT), and induced lightning. unidirectional lines ESD protection >15kV TVS diodes are characterized by their high surge @ Low Leakage Current capability, low operating and clamping voltages, and fast response time. This makes them ideal for use as : board level protection of sensitive semiconductor MECHANICAL CHARACTERISTICS: components. The SMDA series is designed to provide JEDEC MS-012AA smail outline package transient suppression on multiple data lines and 1/0 Solder temperature : 265C for 10 seconds ports. The low profile SO-8 design allows the user to Readily solderable terminals protect up to four data and I/O lines with one package. Pin #1 marked with dot on body The SMDA series is suitable protection for sensitive TTL Marking : Logo, part number, and date code and CMOS ICs such as microprocessors, I/O e Packaging : Tube or 12mm tape per EIA 481-1 transceivers, ASICs, transducers, and CMOS memory. The SMDA series TVS diode arrays will meet the surge SCHEMATIC requirements of IEC 1000-4-2 (Formerly IEC 801-2), Level 4, Human Body Mode!" for air and contact UNIDIRECTIONAL BIDIRECTIONAL discharge.
