AC/DC Characteristics
AC/DC characteristics involve the spread of values guaranteed within the spec-
ified voltage and ambient temp. range. Typical characteristics are the median
of the production. The device performance parameters marked with were
measured on an Infineon evaluation board as desdribed in Section 5.2. Cur-
rents flowing into the device are denoted as positive currents and vice versa.
