Surface Mount – 600W > SMBJ series
TVS Diodes
Description
Agency Approvals
The SMBJ series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
Excellent clamping
capability
Low incremental surge
resistance
Typical IR less than 1μA
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
IEC 61000-4-4
• Built-in strain relief
Fast response time:
typically less than 1.0ps
from 0V to VBR min
• 600W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
High temperature to reflow
soldering guaranteed:
260°C/30sec
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)
UL Recognized to ANSI/
UL 497B: Protectors for
Data Communications and
Fire-Alarm Circuits.
Applications
TVS components are ideal for the protection of I/O
Interfaces, VCC bus and other vulnerable circuits used in
Telecom, Computer, Industrial and Consumer electronic
applications.
