Thomas Road Scottsdale, AZ 85251 Tel: (480) 941-6300 Fax: (480) 947-1503 SMDA03C-8 thru SMDA24C-8 TVSarrayTM Series TM DESCRIPTION (300 watt) This 14 pin 8 line Bi-directional array 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 TRANSIENT VOLTAGE SUPPRESSOR (TVS) Diode Arrays have a peak power of 300 watts for an 8/20 sec pulse and are designed to protect 3.0/3.3 volt components such as DRAM's, SRAM's, CMOS, HCMOS, HSIC, and low voltage interfaces up to 24 volts. FEATURES * * * * Protects 3.0/3.3 up through 24V Components Protects 8 lines Bi-directional Provides electrically isolated protection SO-14 Packaging MECHANICAL * * * * * Molded SO-14 Surface Mount Weight: 0.127 grams (approximate) Body Marked with Logo, and device number Pin #1 defined by DOT on top of package Encapsulation meets UL 94V-0 MAXIMUM RATINGS * * * * Operating Temperatures: -550 C to +1500 C Storage Temperature: -550 C to +1500 C 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 (OPTIONAL) Carrier tubes 55 pcs per (STANDARD) ELECTRICAL CHARACTERISTICS@ 250C Unless otherwise specified STAND OFF VOLTAG E VWM VOLTS MAX SMDA03C-8 SMDA05C-8 SMDA12C-8 SMDA15C-8 SMDA24C-8 SDL8 SDB8 SDD8 SDF8 SDH8 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 7.0 9.8 19.0 24.0 43.0 CLAMPING VOLTAGE VC @ 5 Amp (FIGURE 2) VOLTS MAX 9.0 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 50 35 TEMPERATURE COEFFICIENT OF VBR aVBR mV/C MAX -5 1 8 11 28 PART NUMBER DEVICE MARKING NOTE: Transient Voltage Suppression (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-8 product is designed for transient voltage suppression protection of components at the board level. It is an ideal product to be used for protection of I/O Transceivers.
