Thermal Resistance
The Acrich2 LED has a thermal resistance of 27℃/W from junction of the LED to the
LED lead.
The maximum junction temperature of the Acrich2 LED package is 125℃, therefore the maximum
lead temperature T

is

j_max
- (Rθ

)
= 125℃ - (27℃/W * 0.58W) = 109.34℃
Although this is the maximum lead temperature, it is recommended to keep the lead temperature
under 70℃.
