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.

Tch

=

Channel temperature (=

junction temperature)

( Pdiss x

RthChS ) +

Power dissipated in the chip. It Rth of device from channel to
