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
Built-in strain relief
Glass passivated chip junction
1500W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%
VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25)) (αT:Temperature Coefficient, typical value is 0.1%)
Excellent clamping capability
Low incremental surge resistance
Meet MSL level 1 per J-STD-020, and high temperature soldering guaranteed: 260C/10sec
Matte tin lead–free Plated
Halogen free and RoHS compliant
Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/ JEDEC J-STD-609A.01)
