Notes:

1. See TYPICAL APPLICATIONS notes to ensure constant junction temperature, low duty cycle pulse testing used.

2. All limits are at 125oC or over the full operating temperature junction range of -40oC to +125oC.

3. The maximum power dissipation is a function of maximum junction temperature, total thermal resistance and ambient temperature.

4. Human body model, 100µF discharged through 1.5KΩ.
