Description
The 1.5SMB Series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• For surface mounted
applications to optimize
board space
• Low profile package
• 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
• ESD protection of data
lines in accordance with
IEC 61000-4-2, 30kV(Air),
30kV (Contact)
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Built-in strain relief
• Glass passivated chip
junction
• 1500W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
• Vx(αBR(1T@:+TαeTmJT=pxVeB(rTRa@Jtu-2r25e5°C))
Coefficient, typical value
is 0.1%)
• Excellent clamping
capability
• Low incremental surge
resistance
• Meet MSL level 1 per
J-STD-020, and high
temperature soldering
guaranteed: 260C/10sec
• 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)
