DiscoverEE Calculated Values
ID [A] Calc. @RthJA max TJ=175°C, TA=25°C	1.3 (conservative) Approx. value as we assume RDS(on)max @ 175 °C = 2.5x RDS(on)max @ 25 °C
ID [A] Calc. @ System RthJA = °C/W, TJ=°C, TA=25°C	7.0 (realistic) Approx. value as we assume RDS(on)max @ 175 °C = 2.5x RDS(on)max @ 25 °C
ID [A] Calc. @RthJC max TJ=175°C, TC=25°C	5.7 (ideal heatsink, Silicon limit) Approx. value as we assume RDS(on)max @ 175 °C = 2.5x RDS(on)max @ 25 °C
PD [W] Calc. @RthJA max TJ=175°C, TA=25°C	0.6 (conservative)
