Description
RoHS
Pb
e3
The SMBJ-HRA High Reliability 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
≤ 1µA for V
R
>
11.10V
• SMT for minimal
board footprint
• 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)
• Built-in strain relief
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• 600W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
