LITE-ON TECHNOLOGY CORPORATION P r o p e r t y o f L i t e - O n O n l y Electrical Optical Characteristics At Ta=25℃ ℃ ℃ ℃ Parameter Symbol Part No. LTST- Min. Typ. Max. Unit Test Condition Luminous Intensity IV S271KRWT 18.0 54.0 mcd IF = 20mA Note 1 Viewing Angle 2θ1/2 S271KRWT 130 deg Note 2 (Fig.6) Peak Emission Wavelength λP S271KRWT 639 nm Measurement @Peak (Fig.1) Dominant Wavelength λd S271KRWT 631 nm Note 3 Spectral Line Half-Width Δλ S271KRWT 20 nm Forward Voltage VF S271KRWT 2.0 2.4 V IF = 20mA Reverse Current IR S271KRWT 10 μA VR = 5V Notes: 1. Luminous intensity 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. 3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
