DiscoverEE Calculated Values
ID [A] Calc. @RthJA max
TJ=150°C, TA=25°C 		1.6 (conservative)
Approx. value as we assume RDS(on)max @ 150 °C = 2x RDS(on)max @ 25 °C
ID [A] Calc. @ System RthJA = °C/W, TJ=°C, TA=25°C 6.3 (realistic)
Approx. value as we assume RDS(on)max @ 150 °C = 2x RDS(on)max @ 25 °C
ID [A] Calc. @RthJC max
TJ=150°C, TC=25°C 		2.6 (ideal heatsink, Silicon limit)
Approx. value as we assume RDS(on)max @ 150 °C = 2x RDS(on)max @ 25 °C
PD [W] Calc. @RthJA max
TJ=150°C, TA=25°C 		0.8 (conservative)
PD [W] Calc. @ System RthJA = 10 °C/W, TJ=150°C, TA=25°C 12.5 (realistic)
