SML-521 Series Light Emitting Diodes Two-color chip LEDs, super small type SML-521 Series The SML-521 Series are two-color chip LEDs, super small type. Due to its small size in dimension and thickness it is suitable for portable electricity which mainly works under battery. Also for high density mounting. !Features 1) 1.5x1.3mm Super small package 2) Thickness of only 0.6mm 3) Green-red, green-orange greenyellow 3types are available !External dimensions (Units : mm) 1.5 1.1 RED, ORANGE YELLOW 2 1 2 1 0.450.05 4 3 (0.6) 1.3 4 3 GREEN (0.225) 0.6 0.6 Cathode index 1.1 R 0. 2 1.6 Electrode 0.450.05 (0.18) Tolerances are 0.1 unless otherwise noted: !Selection guide Emitting color Red/Green Lens Milky white SML-521MUW SML-521MDW SML-521MYW Orange/Green Yellow/Green SML-521 Series Light Emitting Diodes !Absolute maximum ratings (Ta=25C) Parameter Power dissipation Forward current Peak forward current Reverse voltage Operating temperature Storage temperature Symbol M PD IF IFP VR Topr Tstg 70 25 60 4 -30~+85 -40~+85 Limits U, D, Y 50 20 mW mA mA V C C Unit Pulse width 1ms Duty 1/5 !Electrical and optical characteristics (Ta=25C) Parameter Color Type SML-521MUW Red Green SML-521MDW Orange Green Yellow Green Forward voltage VF (V) Typ. 1.9 2.2 1.9 2.2 1.9 2.2 2.5 2.8 2.5 2.8 2.5 2.8 20 100 4 Reverse current Luminous intensity IV (mcd) Min. 22 5.6 22 5.6 22 5.6 Peak wavelength Spectral line half width Cond.
