when VBR min>12V
• For surface mounted
applications to optimize
board space
• Low profile package
• 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

typically less than 1.0ps
from 0 Volts to VBR min
• Glass passivated junction
• Low inductance
• High temperature
to reflow soldering
guaranteed: 260°C/40sec
• VBR @ TJ= [email protected]°C
x (1+αT x (TJ - 25))
(αT:Temperature
Coefficient, typical value
is 0.1%)
• Plastic package is
flammability rated
V-0 per Underwriters
Laboratories
• Meet MSL level1, per
J-STD-020, LF maximun
peak of 260°C
• Matte tin lead–free Plated
• Halogen free and RoHS
compliant
• Pb-free E3 means 2nd
level interconnect is
Pb-free and the terminal
finish material is tin(Sn)
(IPC/JEDEC J-STD609A.01)
Notes:
1. Non-repetitive current pulse, per Fig.4 and derated above TJ (initial) =25ºC per Fig. 3.
Applications
2.Mounted on 5.0x5.0mm copper pad to each terminal.
TVS devices are ideal for the protection of I/O Interfaces,
VCC bus and other vulnerable circuits used in Telecom,
Computer, Industrial and Consumer electronic
applications.
3.Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
device only.
4.VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
5. The PPPM of stacked-die parts is 600W and please contact littelfuse for the detail
stacked-die parts.
