* stand?o voltage: 2.5 v ? 7.0 v * peak power up to 200 watts @ 8 x 20 s pulse * low leakage * response time is typically < 1 ns * esd rating of class 3 (> 16 kv) per human body model * iec61000?4?2 level 4 esd protection * iec61000?4?4 level 4 eft protection * the esd5z series is designed to protect voltage sensitive components from esd and transient voltage events. excellent clamping capability, low leakage, and fast response time, make these parts ideal for esd protection on designs where board space is at a premium. because of its small size, it is suited for use in cellular phones, portable devices, digital cameras, power supplies and many other portable applications. features: description: transient voltage suppressors for esd protection lea d( p b)- f r ee p b esd5z series weitron http://ww w .weitron.com.tw 1/3 rev.a 11-aug-09 sod-523 outline dimensions unit:mm transient voltage suppressors 200 watts 2.5-7.0 volts ?t? se a ting plane b a ?x? ?y? d 2 pl t m 0.08 (0.003) x y c s j k dim millimeters a 1.1 0 1.2 0 1.30 b 0.7 0 0.8 0 0.90 c 0.5 0 0.6 0 0.70 d 0.2 5 0.3 0 0.35 j 0.0 7 0.1 4 0.20 k 0.1 5 0.2 0 0.25 s 1.5 0 1.6 0 1.70 1 2 sod-523/sc-79 1 2 max nom min
