LTC7106EDDB and LTC7106IDDB difference?

Found it by myself:

Note 2: The LTC7106 is tested under pulsed load conditions such that TJ ≈ TA. The LTC7106E is guaranteed to meet performance specifications from 0°C to 85°C. Specifications over the –40°C to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. The LTC7106I is guaranteed over the –40°C to 125°C operating junction temperature range. High junction temperatures degrade operating lifetimes; operating lifetime
