A.1.7 Operating Conditions
This section describes the operating conditions of the device. Unless otherwise noted those conditions
apply to all the following data.
NOTE
Please refer to the temperature rating of the device (C, V, M) with regards to
the ambient temperature T
A
and the junction temperature T
J
. For power
dissipation calculations refer to Section A.1.8, “Power Dissipation and
Thermal Characteristics”.
