In a datasheet review we found that there is some information missing and we decided to add further diagrams. Additionally, we have to make some minor changes in the dimensions of the tape drawing and improved technical data. For details, please refer to the table below, where all changes are explained. VLMU3500-385-120 VLMU3500-385-060 X X X X X X X X X X X X Modifications Package dimensions: Arrangement of polarity marks corrected in drawing Package dimensions: Visible internal structure added in top view for better identification of polarity Fig. 5 - Maximum Forward Current vs. Ambient Temperature updated (Top only up to 85°C, dotted line above 85°C) Diagrams added: Fig. 6 - Relative Radiant Flux vs. Ambient Temperature Fig. 7 - Change of Peak Wavelength vs. Ambient Temperature Fig. 8 - Change of Forward Voltage vs. Ambient Temperature Tape and reel dimensions: pocket depth from 3.5 mm to 3.2 mm Thermal resistance: Junction to solder point changed from 12°C/W to 8°C/W Drying time at 60°C + 5°C and <5% RH for all device containers changed from 96 h to 24 h There is no influence on form / fit / function of the products. The updated datasheets, Rev. 1.1 from 02-Feb-2016, have replaced datasheets from Rev. 1.0, 18-July2015. Hyperlinks to the new versions are included in this Fast Fact and will be available on the Vishay website by the end of February 2016.
