Notes:
1. Case temperature of 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, ld, 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 HDSP-A101 series displays are recommended.
6. For low current operation the HER HDSP-7511 series displays are recommended.
7. For low current operation the Yellow HDSP-A801 series displays are recommended.
8. For low current operation the Green HDSP-A901 series displays are recommended.
9. The yellow (HDSP-7400) and Green (HDSP-7800) displays are categorized for dominant wavelength. The category is designated by a number
