Pulse-testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must
be taken into account separately. All characteristics are measured with a 2-
μ
F capacitor across the input and a 1-
μ
F capacitor across the output.
This specification applies only for dc power dissipation permitted by absolute maximum ratings.
