Symbol		Parameter	Conditions				Min	Typ	Max	Unit
Rth(j-a)		thermal resistance from junction	in free air	[1] [2]
		to ambient
		SOD123F					-	-	330	K/W
		SOD323F					-	-	350	K/W
				[1] [3]			-	-	150	K/W
Rth(j-sp)		thermal resistance from junction
		to solder point
		SOD123F					-	-	60	K/W
		SOD323F					-	-	55	K/W

[1]Schottky barrier diodes thermal run-away has to be considered, as in some applications the reverse power

losses PR are a significant part of the total power losses. Nomograms for determining the reverse power losses PR and IF(AV) rating will be available on request.
