    8. Indoor/Outdoor Commercial and Residential Architectural.
    9. Edge_lit signs (Exit, point of sale).
    10. LCD Backlights/Light Guides.



  1. Absolute Maximum Ratings at Ta=25
  2. Parameters Symbol Rating Units
    Forward Current IF 500 mA
    Peak Pulse Current (tp≤100μs, Duty cycle=0.25) I pulse 700 mA
    Reverse Voltage VR 5 V
    LED Junction Temperature Tj 125
    Operating Temperature Range Topr -40 to +80

  3. Proper current derating must be observed to maintain junction temperature below the maximum.
  4. LEDs are not designed to be driven in reserve bias.

    Electrical Optical Characteristics at Ta=25

    Parameters Symbol Min. Typ. Max. Unit Test Condition
    Viewing Angle [1] 1/2 --- 120 -- Deg IF=350mA
    Forward Voltage [2] VF 1.6 --- 2.2 V IF=350mA
    Reverse Current IR --- --- 10 µA VR=5V
    Peak Emission Wavelength λp --- 730 --- nm IF=350mA
    Dominant Wavelength λd ---- 730 ---- nm IF =350mA
    Spectrum Radiation Bandwidth Δλ --- 10 --- nm IF=350mA
    Power Intensity Pv 160 --- 240 mw IF=350mA


  6. 2θ1/2 is the off axis angle from lamp centerline where the luminous intensity is 1/2 of the peak value.
  7. Forward Voltage measurement tolerance : ±0.1V



    1. Luminous Radiant is measured with a light sensor and filter combination that approximates the CIE eye-response curve.

    2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
