Notes:

1. Non-repetitive current pulse, per Fig.4 and derated above T

2. Mounted on 5.0x5.0mm copper pad to each terminal.

3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional

device only.

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.

Applications

TVS devices are ideal for the protection of I/O Interfaces,

V

Computer, Industrial and Consumer electronic

applications.

• Same power as standard

SMB devices (600 W)

• SMA low profile package:

less than 1.1 mm

• 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

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

• Low inductance, excellent

clamping capability

• Fast response time:

typically less than 1.0ns

from 0 Volts to V

• Built-in strain relief

• Glass passivated junction

• Typical I

• High temperature

to reflow soldering

guaranteed: 260°C/40sec

• V

Coefficient, typical value

is 0.1%)

• Plastic package is

flammability rated

V-0 per Underwriters

Laboratories

• Meet MSL level1, per

J-STD-020, LF maximun

• 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)
