ESD9DXX

ESD9DXX Series Surface Mount TVS For ESD Protection Diode P b Lead(Pb)-Free General Description: The ESD9DXX Series 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. TRANSIENT VOLTAGE SUPPRESSORS 100 WATTS 3.3-5.0 VOLTS Applications: *Cellular phones audio *MP3 players *Digital cameras *Portable applicationss *mobile telephone SOD-923 Features: *Small Body Outline Dimensions:0.039” x 0.024” (1.0 mm x 0.60 mm) *Low Body Height: 0.017” (0.43 mm) Max *Stand−o Voltage: 3.3 V − 5.0 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 *These are Pb−Free Devices SOD-923 Outline Dimensions −X− D −Y− E 1 b 2X 0.08 (0.0032) Unit:mm MILLIMETERS DIM A b c D E HE L MIN NOM MAX 2 XY A L C HE 0.36 0.15 0.07 0.75 0.55 0.95 0.05 0.40 0.20 0.12 0.80 0.60 1.00 0.10 0.43 0.25 0.17 0.85 0.65 1.05 0.15 WEITRON http://www.weitron.com.tw 1/4 16-Aug-07 ESD9DXX Series Maximum Ratings(T =25˚C Unless Otherwise Noted) A Characteristic Symbol Value Unit Peak Power Dissipation (tp=8/20 µs) Total Power Dissipation on FR-5 Board (Note1) @ Ta=25°C IEC61000-4-2(ESD) ESD Voltage air discharge contact discharge Per Human Body Model PPP PD 100 150 ±15 ±8 16 W mW KV KV °C °C Lead Solder Temperature -Maximum (10 second Duration) Junction and Storage Temperature Range TL TJ ,Tstg 260 -55 to +150 Stresses exceeding Maximum Ratings may damage the device.
