e3
The TPSMF4L 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, and it’s especially suitable for high reliability and
automotive application.
Features
• Hi reliability application
and automotive grade
AEC Q101 qualified
• 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
