Notes:
1. Case temperature of the device immediately prior to the intensity measurement is 25°C.
2. The digits are categorized for luminous intensity. The intensity category is designated by a letter on the side of the package.
3. The dominant wavelength, λ_d, is derived from the CIE chromaticity diagram and is that single wavelength which defines the color of
the device.
4. Typical specification for reference only. Do not exceed absolute maximum ratings.
5. For low current operation, the AlGaAs Red HDSP-N100 series displays are recommended. They are tested at 1 mA dc/segment and
are pin for pin compatible with the HDSP-N150 series.
6. The Yellow (HDSP-4200) and Green (HDSP-8600) displays are categorized for dominant wavelength. The category is designated by
a number adjacent to the luminous intensity category letter.
