VR = 5V, Note 5

Note: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE

(Commission International De L'Eclairage) eye-response curve.

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

3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single

wavelength which defines the color of the device.

4. The Iv guarantee should be added ±15% .

5. Reverse voltage (VR) condition is applied for IR test only. The device is not designed for

reverse operation.
