Description
The SMA6L series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
SMA low profile package has the same electronical
performance as the SMB package but with low height
profiles (1.1mm) in the industry.
Features
• SMA low prole package:
less than 1.1 mm
• Same power as standard
SMB devices (600 W)
• Footprint compatibility
with standard SMA and
SMB products (easy to
layout)
• 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 (IEC801-2)
• EFT protection of data
lines in accordance with
• Low inductance, excellent
clamping capability
• Fast response time:
typically less than 1.0ns
from 0 Volts to V
BR

• Built-in strain relief
• Glass passivated junction
• Typical I
less than 1µA
R
above 12V
• High temperature
soldering: 260°C/40
seconds at terminals
•
VBR @TJ= VBR@25°C × (1+αT
x (T
- 25))
J
(αT: Temperature Coefcient)
• Meet MSL level1, per
J-STD-020, LF maximum
peak of 260°C
• Matte tin lead–free plated
• Halogen free and RoHS
compliant
IEC 61000-4-4 (IEC801-4)
Applications
TVS devices are ideal for the protection of I/O Interfaces,
V
bus and other vulnerable circuits used in Telecom,
CC
Computer, Industrial and Consumer electronic applications.
