SMA6L Series
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 lowest height
profiles (1.1mm) in the industry.
Features
Maximum Ratings andThermal Characteristics
(TA=25OC unless otherwise noted)
• SMA low profile package:
less than 1.1 mm
• Same power as standard
.• Low inductance,
excellent clamping
capability

SMB devices (600 W)
• Fast response time:
typically less than 1.0ns
from 0 Volts to VBR min
• Built-in strain relief
• Glass passivated junction
•Typical IR less than 1µA
above 12V
• High temperature
soldering: 260°C/40
seconds at terminals
• 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)
