Note 1: Average power for time period τ where τ is the time constant (in µs) of the transient diode current during a hot-plug event.

For, example, if τis330µs,themaximumaveragepoweris0.793W.Peakcurrentmustneverexceed2A.Actualaverage

power during hot-plug must be calculated from the diode current waveform for the application circuit and compared to the

maximum rating.

(VDCIN=5V,VAA = VDDL=3.3V,TA = TMIN to TMAX, unless otherwise noted, where TMIN=-40°CandTMAX=+105°C.Typicalvalues

are at TA=+25°C.Operationiswiththerecommendedapplicationcircuit.)

Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these

or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.
