ESD5Z12 Transient Voltage Suppressors for ESD Protection TRANSIENT VOLTAGE SUPPRESSORS 240 WATTS 12 VOLTS P b Lead(Pb)-Free Description: * The ESD5Z12 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. 1 2 SOD-523/SC-79 Features: * Stand−off Voltage: 12 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 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 J WEITRON http://www.weitron.com.tw K 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 21-Jan-09 ESD5Z12 Maximum Ratings(TA=25˚C Unless Otherwise Noted) Symbol Value Unit 16 400 kV V 30 30 kV PD 150 mW RθJA 833 °C/W Lead Solder Temperature -Maximum TL 260(10s) °C Junction Temperature Range TJ 150 °C Storage Temperature Range Tstg -55 to +150 °C Characteristic ESD Voltage Per Human Body Model Per Machine Model Electrostatic discharge IEC61000-4-2 Air discharge IEC61000-4-2 ContactAir discharge Total Power Dissipation on FR−5 Board1, @ TA = 25°C Thermal Resistance Junction to Ambient Stresses exceeding Maximum Ratings may damage the device.
