KSPDA0211EA Precautions against UV light exposure ∙ When UV light irradiation is applied, the product characteristics may degrade. Such examples include degradation of the product’s UV sensitivity and increase in dark current. This phenomenon varies depending on the irradiation level, irradiation intensity, usage time, and ambient environment and also varies depending on the product model. Before employing the product, we recommend that you check the tolerance under the ultraviolet light environment that the product will be used in. 4 Si photodiodes S12698 series Related information www.hamamatsu.com/sp/ssd/doc_en.html Precautions ∙ Disclaimer ∙ Metal, ceramic, plastic package products Technical information ∙ Si photodiode / Application circuit example Information described in this material is current as of November, 2015.
