and automotive grade AEC
Q101 qualified
resistance
Typical IR ≤ 1µA for VR > 10V
•
• Surface mount component
to minimize 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
• ESD protection of data
lines in accordance with
IEC 61000-4-2, 30kV(Air),
30kV (Contact)
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Glass passivated chip
junction
• High temperature
soldering guaranteed:
260°C/10 seconds at
terminals
• UL Recognized compound
meeting flammability
rating V-0.
