Transient Voltage Suppression Diodes
Surface Mount – 1500W > SMCJ series
SMCJ Series
Uni-directional
Bi-directional
Description
RoHS
Pb
e3
The SMCJ series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• 1500W 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
• Built-in strain relief
• 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
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.
Additional Infomarion
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• Glass passivated chip
junction
• High temperature
to reflow soldering
guaranteed: 260°C/40sec

• 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)
