exceedꢀtheꢀMaximumꢀPowerꢀDissipation,ꢀgivenꢀbyꢀ
PD(MAX).ꢀThereforeꢀPDꢀ≤ꢀPD(MAX).ꢀFromꢀtheꢀdiagramꢀitꢀ
canꢀbeꢀseenꢀthatꢀalmostꢀallꢀofꢀthisꢀpowerꢀisꢀgeneratedꢀ

Thermal Considerations
Theꢀmaximumꢀpowerꢀdissipationꢀdependsꢀonꢀtheꢀ
thermalꢀresistanceꢀofꢀtheꢀpackage,ꢀtheꢀPCBꢀlayout,ꢀ
theꢀrateꢀofꢀtheꢀsurroundingꢀairflowꢀandꢀtheꢀdifferenceꢀ
betweenꢀtheꢀjunctionꢀandꢀambientꢀtemperature.ꢀTheꢀ
maximumꢀpowerꢀdissipationꢀcanꢀbeꢀcalculatedꢀusingꢀ

bothꢀsteadyꢀstateꢀandꢀtransientꢀcurrents,ꢀtheꢀimportantꢀ
currentꢀtoꢀconsiderꢀisꢀtheꢀaverageꢀorꢀmoreꢀpreciselyꢀ
theꢀRMSꢀcurrentꢀwhichꢀisꢀtheꢀvalueꢀofꢀcurrentꢀthatꢀwillꢀ
