Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

6. Performance guaranteed over the indicated operating temperature range by design and/or characterization production tested at TJ = TA =

25

°C. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

7. A proper heatsinking and/or low duty cycle pulse techniques are used to operate the device within the Safe Operating Area.

8. Guaranteed by design
