Pulse-testing techniques 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 0.33-
μ
F capacitor across the input and a 0.1-
μ
F capacitor across the output.
This specification applies only for dc power dissipation permitted by absolute maximum ratings.
