2 / 9 page  www.vishay.com 2 Document Number 81783 Rev. 1.2, 21-Jul-08 Vishay Semiconductors VLMW611. For technical support, please contact: LED@vishay.com Note: Not designed for reverse operation 1) T amb = 25 °C, unless otherwise specified Note: Not designed for reverse operation 1) T amb = 25 °C, unless otherwise specified 2) Forward voltages are tested at a current pulse duration of 1 ms and a tolerance of ± 0.05 V 3) Theoretical correlation for 120° emission angle Note: Luminous intensity is tested at a current pulse duration of 25 ms and an accuracy of ± 11 %. The above type numbers represent the order groups which include only a few brightness groups. Only one group will be shipped on each reel (there will be no mixing of two groups on each reel). In order to ensure availability, single brightness groups will not be orderable. In a similar manner for colors where wavelength groups are measured and binned, each single wavelength group is packed in a single reel. In order to ensure availability, single wavelength groups can not be ordered. ABSOLUTE MAXIMUM RATINGS 1) VLMW611.
