TRANSIENT VOLTAGE
SUPPRESSORS
100 WATTS
3.3-5.0 VOLTS
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.
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−off 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
