short from over-specified
voltage or current
• hisker test is conducted
W
based on JEDEC
JESD201A per its table 4a
and 4c
• EC-61000-4-2 ESD
I
30kV(Air), 30kV (Contact)
• SD protection of data
E
lines in accordance with
IEC 61000-4-2
• FT protection of data
E
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
• 600W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
• igh temperature
