Note:

1. All parameters are guaranteed over the virtual junction temperature range by design, but only 100% tested at 125 ℃ ambient temperature for dies on wafer level, and in addition to this 100% tested at 25 ℃ambient temperature for cased products; unless specified otherwise. For bare dies, all parameters are only guaranteed with the backside of the die connected to ground.
