1. Performance guaranteed over the indicated operating temperature range by design and/or characterization tested at T J = T A = 25 _ C. Low
duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
2. Refer to Application Information section.
3. Values based on design and/or characterization.
