ESD5Z Series Transient Voltage Suppressors for ESD Protection TRANSIENT VOLTAGE SUPPRESSORS 200 WATTS 2.5-7.0 VOLTS P b Lead(Pb)-Free Description: * 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. 1 2 SOD-523/SC-79 Features: * Stand−off Voltage: 2.5 V − 7.0 V * Peak Power up to 200 Watts @ 8 x 20 µs 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 SOD-523 Outline Dimensions Unit:mm −X− A −Y− MILLIMETERS B 1 2 D 2 PL 0.08 (0.003) M T X Y C K J WEITRON http://www.weitron.com.tw S −T− DIM MIN NOM MAX A B C D J K S 1.10 0.70 0.50 0.25 0.07 0.15 1.50 1.20 0.80 0.60 0.30 0.14 0.20 1.60 1.30 0.90 0.70 0.35 0.20 0.25 1.70 SEATING PLANE 1/3 Rev.A 11-Aug-09 ESD5Z Series Maximum Ratings(TA=25˚C Unless Otherwise Noted) Symbol Value Unit 16 400 kV V Electrostatic discharge IEC61000-4-2 Air discharge IEC61000-4-2 ContactAir discharge 30 30 kV Electrostatic discharge IEC61000-4-4 40 A Characteristic ESD Voltage Per Human Body Model Per Machine Model Total Power Dissipation on FR−5 Board1, @ TA = 25°C PD 100 mW Lead Solder Temperature -Maximum TL 260(10s) °C Junction Temperature Range TJ 150 °C Storage Temperature Range Tstg -55 to +150 °C Maximum ratings are those values beyond which device damage can occur.
