Description
The 1.5SMC series is designed specically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• For surface mounted
applications to optimize
board space
• Low prole package.
• Typical failure mode is
short from over-specied
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 (IEC801-2)
• EFT protection of data
lines in accordance with
IEC 61000-4-4 (IEC801-4)
• Built-in strain relief
•
VBR @TJ= VBR@25°C × (1+αT
x (TJ - 25))
(αT: Temperature Coefcient)
• Glass passivated chip
junction
• 1500W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• Excellent clamping
capability
• Low incremental surge
resistance
• Typical I
less than 1µA
R
above 13V
• High temperature
soldering guaranteed:
260°C/40 seconds at
terminals
• Plastic package has
underwriters laboratory
ammability 94V-O
• Meet MSL level1, per
J-STD-020, LF maximum
peak of 260°C
• Matte tin lead–free plated
• Halogen free and RoHS
compliant
Applications
TVS devices are ideal for the protection of I/O Interfaces,
V
bus and other vulnerable circuits used in Telecom,

For bidirectional type having VR of 10 volts and less, the IR limit is double.
For parts without A , the V
is ± 10% and Vc is 5% higher than with A parts.
