Functional Diagram
Description
The P4SMA series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• 400W peak pulse power
capability at 10/1000µs
waveform, repetition rate
(duty cycles):0.01%
• Excellent clamping
capability
• Low incremental surge
resistance
wTyhpeicnaVl IBRR
less than
min>12V
1μA
• Optimized surface mount
footprint for minimal PCB
space impact
• Low profile package
• Typical failure mode due
to exceeding maximum
ratings is a short circuit
condition
• Whisker test conducted
based on Table 4a and 4c
of JEDEC JESD201A
• IEC-61000-4-2 ESD
30kV(Air), 30kV (Contact)
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Built-in strain relief
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• High temperature
to reflow soldering
guaranteed: 260°C/40sec
• Vx(αB(R1T:+@TαeTmTJ=pxeV(rBTaRJt@u-2r2e55°)C)
Coefficient, typical value
is 0.1%)
• UL Recognized epoxy
meeting flammability
classification V-0
• 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)
