5.1.3 AC/DC Characteristics at T_AMB = 25°C
AC/DC characteristics involve the spread of values guaranteed within the spe-
cified voltage and ambient temperature range. Typical characteristics are the
median of the production. Currents flowing into the device are denoted as po-
sitive currents and vice versa.
The device performance parameters marked with s were measured on an
Infineon evaluation board as described in Section 5.2.
