SMDA03 thru SMDA24C and SMDB03 thru SMDB24C 4 LINE TVSarray TM SCOTTSDALE DIVISION APPEARANCE This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged in an SO-8 configuration giving protection to 4 unidirectional or bi-directional data or interface lines. It is designed for use in applications where protection is required at the board level from voltage transients caused by electrostatic discharge (ESD) as defined in IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and effects of secondary lightning. These TVS arrays have peak pulse power ratings of 300 watts (SMDA) and 500 watts (SMDB) for an 8/20 sec pulse. They are suitable for protection of sensitive circuitry consisting of TTL, CMOS, DRAM's, SRAM's, HCMOS, HSIC and low-voltage interfaces from 3.3 volts to 24 volts IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com FEATURES * * * PACKAGING * * * Protects 3.0/3.3 volt up to 24 volt components Protects 4 unidirectional or bidirectional lines Provides electrically-isolated protection Tape & Reel per EIA Standard 481 13 inch reel; 2,500 pieces (STANDARD) Carrier tubes; 95 pcs (OPTIONAL) MAXIMUM RATINGS * * * * * WWW .
