SM16LC03 thru SM16LC24, e3 TVS ArrayTM Series SCOTTSDALE DIVISION APPEARANCE SO-16 WWW . Microsemi .C OM DESCRIPTION This 16 pin 8-line Low Capacitance Unidirectional 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 10004-2, 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 500 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. IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com FEATURES * * * * * APPLICATIONS / BENEFITS Protects 3.0/3.3 up through 24 V Components Protects 8 lines Unidirectional Provides electrically isolated protection SO-16 Packaging RoHS Compliant devices available by adding "e3" suffix * * * * * MAXIMUM RATINGS * * * * 0 Low Capacitance Unidirectional TVS Array (8) Protects: DRAM's, SRAM's, CMOS, HCMOS, HSIC RS-232, RS-422, RS-423, RS-449 data rates: 10 Mbs WAN Equipment: Multiplexers, Routers, ISP, CSU/DSU Multi-mode Transceiver Protection MECHANICAL AND PACKAGING 0 Operating Temperatures: -55 C to +150 C Storage Temperature: -550C to +1500C Peak Pulse Power: 500 Watts (8/20 sec, Figure 1) Pulse Repetition Rate: <.01% * * * * * * * * * * ELECTRICAL CHARACTERISTICS Molded SO-16 Surface Mount Finish: Tin-Lead or RoHS Compliant matte-Tin plating solderable per MIL-STD-750, method 2026 Weight: 0.128 grams (approximate) Body Marked with Logo, and device number Pin #1 defined by DOT on top of package Pins#1 thru 8 are the anodes of each TVS (biased negative with respect to cathodes pins#9 thru 16) Encapsulation meets UL 94V-0 Tape & Reel EIA Standard 481-1-B Carrier tubes 48 pieces per (STANDARD) 13 inch reel 2,500 pieces (OPTIONAL) 0 @ 25 C Unless otherwise specified Application: The SM16LCXX product is designed for unidirectional transient voltage suppression protection of components at the board level. It is an ideal product to be used for protection of I/O Transceivers. See separate data sheet for bidirectional TVS in the SM16LCXXC series (with C suffix).
