Transient Voltage Suppression Diodes
Surface Mount – 600W > P6SMB series
P6SMB Series
Uni-directional
Bi-directional
Description
RoHS
The P6SMB series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• Excellent clamping
capability
• Low incremental surge
resistance
• Typical I
R
less than 1µA
above 12V
• 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
• 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)
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.
• Built-in strain relief
• 600W peak pulse power
capability at 10×1000μs
waveform, repetition rate
(duty cycles):0.01%
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• Typical maximum
temperature coefficient
