Pulse factor:

Ptot-max should not exceed the absolute maximum rating for the dissipated power PPulse = ” Pulse peak power ” = 2 W

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.
