The maximum internal resistor temperature is 175°C. To specify an appropriate heatsink use the following formula : RqH = TMAX - ( P x RqR ) - TA P Where: R qH = Thermal Resistance of Heatsink ( K/W ) R qR = Thermal Resistance of Resistor ( K/W ) T MAX = Maximum Temperature of Resistor T A = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W ) 100 120 25 50 85 100 115 130 145 155 Temperature of the backplate(°C) Power (% from nominal power) Note: Back plate is isolated from both pins.
