description the SESDXXXWB series is designed to protect voltage sensitive components from esd. excellent cl amping capability, low leakage, and fast response time provide best in class protection on designs that are exposed to esd. because of its sm all size, it is suited for use in cellular phones, mp3 players, digita l cameras and many other portable applications where board s pace is at a premium. features z stand?off voltage: 3.3 v? 12 v z low leakage z response time is typically < 1 ns z esd rating of class 3 (> 16 k v) per human body model z iec61000 ?4 ? 2 level 4 esd protection z these are pb ? free devices maximum ratings @ta =25 parameter symbol limit unit iec61000 ?4 ? 2(esd) contact 30 kv esd v oltage per human body model per machine model 16 400 kv v total power d issipation on fr-5 b oard (note 1) p d 100 mw thermal resistance junction ?to ? ambient r ja 1250 / w lead solder temperature ? maximum (10 second duration) t l 260 junction and storage t emperature r ange t j, t stg -55 ~ +150 stresses exceeding m aximum r atings may damage the device. maximum r atings are stress ratings only. functional operation above the reco mmended. operating c onditions is no t implied. extended exposure to stresses above the r ecommended o perating c ond itions may affect device reliability. 1. fr ? 5 = 1.0 x 0.75 x 0.62 in. wbfbp-02c (1 .00.60.5) unit: mm willas electronic corp. 2012-09 z transient voltage suppressors for esd protection SESDXXXWB
