SMF3.3

Surface Mount – 200W

RoHS

Pb e3

Description

SMF3.3 is designed specifically to protect sensitive electronic

equipment from voltage transients induced by lightning and other

transient voltage events.

Features and Benefits

■ 200W peak pulse power

capability at 10/1000µs

waveform, repetition rate

(duty cycle): 0.01%

■ EFT protection of data lines in

accordance with IEC 61000-

4-4

■ Fast response time: typically

less than 1.0ns from 0 Volts

to VBR min

■ 1200W peak pulse power

capability at 8/20us waveform

■ Excellent clamping capability

■ High temperature soldering:

260°C/30 seconds at

terminals

Uni-directional

■ Compatible with industrial

standard package SOD-123FL

■ Built-in strain relief

■ Low proﬁle: maximum height

of 1.08mm.

Additional Information

■ Meet MSL level1, per J-STD-

020C, LF maximun peak of

260°C

■ For surface mounted

applications to optimize board

space

■ Matte tin lead–free plated

■ Typical failure mode is short

from over-speciﬁed voltage or

current

■ Halogen-free and RoHS-

compliant

Resources

Accessories

Samples

■ Pb-free E3 means 2nd level

interconnect is Pb-free and

the terminal ﬁnish material is

tin(Sn) (IPC/JEDEC J-STD-

609A.01)

■ Whisker test is conducted

based on JEDEC JESD201A

per its table 4a and 4c

Agency Approvals
