MCC SMDA03C-7 THRU SMDA24C-7 omponents 21201 Itasca Street Chatsworth !"# $ % !"# TVSarray Series DESCRIPTION (300 watt) This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged in an SO-8 configuration giving protection to 7 Bidirectional 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 1000-4-2, electrical fast transients (EFT) per IEC 1000-4-4 and effects of secondary lighting. These TVS arrays have a peak power rating of 300 watts for an 8/20µsec pulse. This array is suitable for protection of sensitive circuitry consisting of TTL, CMOS DRAM’s, SRAM’s, HCMOS, HSIC microprocessors, and I/O transceivers. The SMDAXXC-7 product provides board level protection from static electricity and other induced voltage surges that can damage sensitive circuitry.

Product selected voltage should be equal to or greater than the continuous peak operating voltage of the circuit to be protected. Application: The SMDAXXC-7 product is designed for transient voltage suppression protection of ESD sensitive components at the board level. It is an ideal product to be used for protection of I/O Transceivers. www.mccsemi.com MCC SMDA03C-7 thru SMDA24C-7 WAVE FORMS 100 Peak Value -- Ipp 8 X 20 Waveform 50 Half-Value -- Ipp 2 0 0 20 10 30 I t td p t -- Time in microsec FIGURE 2 Pulse Wave Form p FIGURE 1 Peak Pulse Power Vs Pulse Time MOUNTING PAD SO-8 CIRCUIT DIAGRAM 0.045±.005 0.245 MIN .160±.005 .030±.005 .050 TYP SO-8 PACKAGE INCHES MILLIMETERS DIM MIN MAX MIN MAX A 0.188 0.197 4.77 5.00 B 0.150 0.158 3.81 4.01 C 0.053 0.069 1.35 1.75 D 0.011 0.021 0.28 0.53 F 0.016 0.050 0.41 G 0.050 BSC 1.27 1.27 BSC J 0.006 0.010 0.15 0.25 K 0.004 0.008 0.10 0.20 L 0.189 0.206 4.80 5.23 P 0.228 0.244 5.79 6.19 www.mccsemi.com
