5 / 25 page www.seoulsemicon.com Product Data Sheet 5 SMJD-XD12W4PX - Acrich3 12.8W Rev1,2, Apr 1, 2016 Thermal Resistance The Acrich3 module is recommended to keep the junction temperature under maximum junction temperature spec. (Table 5) LED lead temperature and IC top case temperature are measured with thermocupler. (Fig1) LED & IC juntion temperatures can be calculated using the formulas below. T s_max = Tj_max - (Rθj-s * Pd) < Example > If LED lead temperature and IC top temerature are 110℃ 1) LED juntion temperature T J = TS + (Rθj-s * Pd) = 110℃ + (9 ℃/W * 0.84W) = 117.56 ℃ 2) IC junction temperature T J = TS + (Rθj-s * Pd) (1) = 110℃ + (11.25 ℃/W * 2.8W) = 141.5℃ * (1) : In the example, P d value is the power consumption of IC when the rated voltage. Part Maximum Junction Temperature [℃] R θ j-s [℃/W] Acrich3 LED 125 9 Acrich3 IC 150 11.25 Notes : Table 5. Thermal information, Ta = 25ºC |
