Transient Voltage Suppression Diodes
Surface Mount – 600W > SMBJ series
SMBJ Series
Uni-directional
Bi-directional
Description
RoHS
Pb
e3
The SMBJ 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
when V
BR
min>12V
• For surface mounted
applications to optimize
board space
• Low profile package
• Typical failure mode is a
short circuit condition for
current events exceeding
component rating
• Whisker test is conducted
based on JEDEC
JESD201A per its table 4a
and 4c
• 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 BV min
• High temperature
to reflow soldering
guaranteed: 260°C/40sec

• Plastic package is
flammability rated V-0 per
UL

• Meet MSL level1, per
J-STD-020, lead-frame
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)

stacked-die components.
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.

For bidirectional type having V
R
of 10 volts and less, the I
R
limit is double.
Components marked with “*” use stacked-die, therefore they have a higher surge capability (typical 1.8*I
PP
).
