RE: Info on DDT-HJS-V2W-1 --- Additional info requested... Min. Current requirement??? ---

WL,

Please add the graph below into DDT-HJS datasheet.

Response :

1) A Graph showing the maximum Current rating vs. Duty Cycle. I do not see a graph in the datasheet. Can you

provide this information?

As graph attached

2) The minimum amount of current that is required to turn-on the LED ?

>1mA in order to ensure brightness homogeneity

Best Regards

Tan

Hi Tan,

Please advice. Thanks.

Allowable Forward Current Vs Duty Ratio

(Tj=25 Deg C, tp<10uS)

Duty Ratio %
