rate (duty cycle):0.01%
u Fast response time: typically less than 1.0ps from 0 Volts to VBR min
u Typical IR less than 2μA above 50V.
u High Temperature soldering: 260°C/40 seconds at terminals
u Typical maximum temperature coefficient ΔVBR = 0.1% ×
VBR@25°C× ΔT
u Plastic package has Underwriters Laboratory Flammability 94V-0
u Matte tin leadfree Plated
u Halogen free and RoHS compliant
u Typical failure mode is short from over-specified voltage or current
u Whisker test is conducted based on JEDEC JESD201A per its table
4a and 4c
u IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)
u ESD protection of data lines in accordance with IEC 61000-4-2
(IEC801-2)
u EFT protection of data lines in accordance with IEC 61000-4-4
(IEC801-4)
