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 prole 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

min

• 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 Coefcient)

• 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.
