Pulse factor:

Ptot-max should not exceed the absolute maximum ratings for the dissipated power PPulse = ” Pulse peak power ”

c) Reliability Considerations

This procedure yields the upper limit for the power dissipation for continuous wave (cw) and pulse

applications which corresponds to the maximum allowed channel temperature. For best reliability keep the

channel temperature low. The following formula allows to track the individual contributions which determine

the channel temperature.
