Notes:
1. Non-repetitive current pulse , per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3.
2. Mounted on copper pad area of 0.2x0.2” (5.0 x 5.0mm) to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
device only, duty cycle=4 per minute maximum.
4. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
• 600W peak pulse power

resistance
• Typical IR less than 1μA
when VBR min>12V
• Optimized surface mount
footprint for minimal PCB
space impact
• Low profile package
• Typical failure mode due
to exceeding maximum
ratings is a short circuit
condition
• Whisker test conducted
based on Table 4a and 4c
of JEDEC JESD201A
• IEC 61000-4-2 ESD
30kV(Air), 30kV (Contact)
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Built-in strain relief
• Fast response time:
typically less than 1.0ps
from 0V to VBR min
• High temperature
to reflow soldering
guaranteed: 260°C/40sec
• VBR @ TJ= VBR@25°C
x (1+αT x (TJ - 25))
(αT:Temperature
Coefficient, typical value
is 0.1%)
• UL Recognized compound
meeting flammability
classification V-0
• 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-STD-609A.01)
Applications
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.
5. The PPPM of stacked-die parts is 800W and please contact littelfuse® for the detail
