* stand?o voltage: 12 v * 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 * the ESD5Z12 is designed to protect voltage sensitive components from esd. excellent clamping capability, low leakage, and fast response time provide best in class protection on designs that are exposed to esd. because of its small size, it is suited for use in - cellular phones, mp3 players, digital cameras and many other portable applications where board space is at a premium. features: description: transient voltage suppressors for esd protection l e a d( p b)- f r ee p b ESD5Z12 weitron http://ww w .weitron.com.tw 1/3 21-jan-09 sod-523 outline dimensions unit:mm transient voltage suppressors 240 watts 12 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
