5.1.3 AC/DC Characteristics at T_AMB = 25°C
AC/DC characteristics involve the spread of values guaranteed within the spec-
ified voltage and ambient temperature range. Typical characteristics are the
median of the production. Currents flowing into the device are denoted as pos-
itive currents and vice versa.
