Functional Diagram
Features
• Glass passivated chip junction in P600 package
• 15kW peak pulse capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%
• Fast response time: typically less than 1.0ps from 0 Volts to BV min
• Excellent clamping capability
• Typical failure mode is short from over-specified voltage or current
• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
• IEC 61000-4-2 ESD 30kV(Air), 30kV (Contact)
• ESD protection of data lines in accordance with IEC 61000-4-2
• EFT protection of data lines in accordance with IEC 61000-4-4
• Low incremental surge resistance
• Typical IR less than 2μA when VBR min>36V
• High temperature to reflow soldering guaranteed: 260°C/40sec / 0.375”, (9.5mm) lead length, 5 lbs., (2.3kg) tension
• VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25)) (αT:Temperature Coefficient, typical value is 0.1%)
• UL Recognized compound meeting flammability rating V-0
• Matte tin lead–free plated
• Halogen free and RoHS compliant
• Pb-free E3 means 2nd level interconnect is Pbfree and the terminal finish material is tin(Sn) (IPC/ JEDEC J-STD-609A.01)
• Recognized to UL 497B
Applications
TVS componants are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuits used in telecom, computer, industrial and consumer electronic applications.
