Description
The SMF series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
SMF package is 50% smaller in footprint when compare
to SMA package and deliverying one of the low height
profiles (1.1mm) in the industry.
Features
• 2 00W peak pulsepower
capability at 10/1000µs
waveform, repetition rate
(duty cycle): 0.01%
•Compatible with
industrial standard
package SOD-123FL
• L ow profile: maximum
height of 1.1mm.
• Low inductance, excellent
clamping capability
• F or surface mounted
applications to optimize
board space
• H igh temperature
to reflow soldering
guaranteed:
260°C/430sec
• 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)
• E SD protection of data
lines in accordance with
IEC 61000-4-2
• E FT protection of data
lines in accordance with
IEC 61000-4-4
• F ast response time:
typically less than 1.0ns
from 0 Volts to VBR min
• 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)
• UL Recognized to UL
497B
