Bi-directional
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
• Typical I
R
less than 1μA
when V
BR
min>12V
• 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:
Applications
TVS devices are ideal for the protection of I/O Interfaces,
V
CC
bus and other vulnerable circuits used in Telecom,
Computer, Industrial and Consumer electronic
applications.
Additional Infomarion
typically less than 1.0ps
from 0V to BV min
