11. 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.
12. Value based on design and/or characterization.
