| 8700 E. Thomas Road Scottsdale, AZ 85251 Tel: (480) 941-6300 Fax: (480) 947-1503 SMDA03C-7 thru SMDA24C-7 TVSarrayTM Series TM 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 8/20sec 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. FEATURES * * * Protects up to 7 Bidirectional lines Surge protection Per IEC 1000-4-2, IEC 1000-4-4 SO-8 Packaging MECHANICAL * * * * Molded SO-8 Surface Mount Weight: 0.066 grams (approximate) Marking: Logo, device number, date code Pin #1 defined by DOT on top of package MAXIMUM RATINGS * * * * Operating Temperatures: -550C to +1500C Storage Temperature: -550C to +1500C Peak Pulse Power: 300 Watts (8/20 sec, Figure 1) Pulse Repetition Rate: <.01% PACKAGING * * * Tape & Reel EIA Standard 481-1-A 13 inch reel 2,500, pieces (OPTIONAL) Carrier tubes 95 pcs per (STANDARD) ELECTRICAL CHARACTERISTICS PER LINE @ 250C Unless otherwise specified STAND OFF VOLTAGE VWM VOLTS MAX SMDA03C-7 SMDA05C-7 SMDA12C-7 SMDA15C-7 SMDA24C-7 SDL7 SDB7 SDD7 SDF7 SDH7 3.3 5.0 12.0 15.0 24.0 BREAKDOWN VOLTAGE VBR @1 mA VOLTS MIN 4 6.0 13.3 16.7 26.7 CLAMPING VOLTAGE VC @ 1 Amp (FIGURE 2) VOLTS MAX 7 9.8 19 24 43 CLAMPING VOLTAGE VC @ 5 Amp (FIGURE 2) VOLTS MAX 9 11 24 30 55 LEAKAGE CURRENT ID @ VWM A MAX 200 40 1 1 1 CAPACITANCE (f=1 MHz) @0V C pF TYP 300 200 75 70 35 TEMPERATURE COEFFICIENT OF VBR aVBR mV/C MAX -5 1 8 11 28 PART NUMBER DEVICE MARKING NOTE: TVS product is normally selected based on its stand off Voltage VWM. 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.
