transient voltage suppressors array for esd protection low capacitance revision january 06, 2014 1 / 3 @ un semiconductor co., ltd. 2014 specifications are subject to change without notice. please refer to www.unsemi.com.tw for current information. LCDAXXC-8 series un semiconductor co., ltd. www.unsemi.com.tw sop-16 the LCDAXXC-8 has been specifically designed to protect sensitive components which are connected to data and transmission lines from over voltages caused by electrostatic discharge (esd), electrical fast transients (eft), and lightning. the low capacitance array configuration of the LCDAXXC-8 allows the user to protect eight high-speed data or i/o lines. they may be used on systems operating from 5 to 24 volts. the high surge capability (500w, tp=8/20 s) makes the LCDAXXC-8 suitable for telecommunications systems operating in harsh transient environments. the low inductance construction minimizes voltage overshoot during high current surges. the features of the LCDAXXC-8 are ideal for protecting multi-protocol transceivers in wan applications such as frame relay systems, routers, and switches. u 500 watts peak pulse power per line (tp=8/20 s) u protects eight i/o lines u low capacitance for high-speed data lines u rohs compliant u iec61000-4-2 (esd) 15kv (air), 8kv (contact) u iec61000-4-4 (eft) 40a (5/50 s) u iec61000-4-5 (lightning) 24a (8/20 s) u high-speed data lines u microprocessor based equipment u test & measurement equipment u notebooks, desktops, and servers u instrumentation u audio/video inputs u lan/wan equipment u peripherals u jedec sop-16 package u molding compound flammability rating : ul 94v-0 u weight 150.0 milligrams (approximate) u quantity per reel : 500pcs u reel size : 7 inch u lead finish : lead free symbol parameter value units p pp peak pulse power (tp=8/20 s waveform) 500 w t l lead soldering temperature 260 (10sec) o c t stg storage temperature range -55 to +150 o c t j operating temperature range -55 to +150 o c iec61000-4-2 (esd) air discharge 15 contact discharge 8 kv iec61000-4-4 (eft) 40 a iec61000-4-5 ( lightning ) 24 a mechanical characteristics d escription feature functional diagram applications m echanical characteristics
