R
θJA
is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. R
θJC
is guaranteed by design while R
θCA
is determined by the user's board design.
a) R
θJA
is 87
°C/W
(steady state) when mounted on a 1 inch² copper pad on FR-4.
b) R
θJA
is 114
°C/W
(steady state) when mounted on a minimum copper pad on FR-4.
白光LED光衰原因之荧光粉性能的衰退 到目前,白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实,盲目地夸大宣传,只能将 LED 行业引向歧途,不正视白光 LED 存在的问题,只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题,白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
