ESD5Z3.3

ESD5Z Series Transient Voltage Suppressors for ESD Protection P b Lead(Pb)-Free TRANSIENT VOLTAGE SUPPRESSORS 200 WATTS 2.5-7.0 VOLTS 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−o 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 −X− A −Y− B 1 D 2 PL 0.08 (0.003) M Unit:mm MILLIMETERS DIM A B C D J K S MIN NOM MAX 2 TXY C K J S −T− SEATING PLANE 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 WEITRON http://www.weitron.com.tw 1/3 Rev.A 11-Aug-09 ESD5Z Series Maximum Ratings(TA=25˚C Unless Otherwise Noted) Characteristic Symbol Value Unit ESD Voltage Per Human Body Model Per Machine Model 16 400 30 30 40 PD TL TJ Tstg 100 260(10s) 150 -55 to +150 kV V kV A mW °C °C °C Electrostatic discharge IEC61000-4-2 Air discharge IEC61000-4-2 ContactAir discharge Electrostatic discharge IEC61000-4-4 Total Power Dissipation on FR−5 Board1, @ TA = 25°C Lead Solder Temperature -Maximum Junction Temperature Range Storage Temperature Range Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and Note.1 FR−5 = 1.0 x 0.75 x 0.62 in.
