Description
RoHS
Pb
e3
The SMBJ-HRA High Reliability series is designed
specifically to protect sensitive electronic equipment from
voltage transients induced by lightning and other transient
voltage events.
Features
• 600W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
• Excellent clamping
capability
• Low incremental surge
resistance
• Typical I
R
less than 1µA
above 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
15kV(Air), 8kV (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
• Built-in strain relief
Applications
TVS devices are ideal for the protection of I/O Interfaces,
V
CC
bus and other vulnerable circuits used in Telecom,
Computer, Industrial and Consumer electronic applications.
• Fast response time:
typically less than 1.0ps
from 0V to BV min

• Glass passivated chip
junction
• High temperature
soldering guaranteed:
260°C/40 seconds at
terminals
• Plastic package is
flammability rated V-0 per
UL 94
• Meet MSL level1, per
J-STD-020, LF maximun
peak of 260

• 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)
