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 delivering one of the lowest height
profiles (1.1mm) in the industry.
Features
•Compatible with
industrial standard
package SOD-123
• For surface mounted
applications to optimize
board space
• Low profile: maximum
height of 1.1mm.
• 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
IEC 61000-4-4 (IEC801-4).
• Low inductance, excellent
clamping capability
• 200W peak pulse power
capability at 10 x 1000µs
waveform, repetition rate
(duty cycle): 0.01%
• 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
• Matte tin lead–free plated
• Halogen-free and RoHS
compliant
Applications
SMF devices are ideal for the protection of I/O interfaces,
V_CC bus and other vulnerable circuit used in cellular phones,
portable devices, business machines, power supplies and
other consumer applications.
