The SMF4L series of SOD-123FL small and flat lead low-
profile plastic package is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Applications
SMF4L devices are ideal for the protection of portable
devices/hard drives, notebooks, V
CC busses, POS terminal,
SSDs, power supplies, monitors, and vulnerable circuit
used in other consumer applications.
• 400W peak pulsepower
capability at 10/1000µs
waveform, repetition rate
(duty cycle): 0.01%
• Compatible with industrial
standard package SOD-
123FL
• Low inductance, excellent
clamping capability
• For surface mounted
applications to optimize
board space
• 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
• Fast response time:
typically less than 1.0ns
from 0 Volts to V
BR min
• High temperature
soldering: 260°C/40
seconds at terminals
• Glass passivated junction
• Built-in strain relief
• Plastic package is
flammability rated V-0 per
Underwriters Laboratories
• Meet MSL level1, per
J-STD-020, LF maximun
peak of 260°C
• 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) (IPC/
JEDEC J-STD-609A.01)
