Notes:
1. Absolute maximum ratings for HER, Yellow, and Green elements of the multicolor arrays are identical to the HDSP-4830/4840/4850 maximum
ratings.
2. See Figure 1 to establish pulsed operating conditions. Maximum pulse width is 1.5 ms.
3. See Figure 2 to establish pulsed operating conditions. Maximum pulse width is 1.5 ms.
4. See Figure 8 to establish pulsed operating conditions. Maximum pulse width is 2 ms.
5. Derate maximum DC current for Red above T
A
= 62°C at 0.79 mA/°C, and AlGaAs Red above T
A
= 91°C at 0.8 mA/°C. See Figure 3.
6. Derate maximum DC current for HER above T
A
= 48°C at 0.58 mA/ °C, Yellow above T
A
= 70°C at 0.66 mA/°C, and Green above T
A
= 37°C at 0.48
mA/°C. See Figure 9.
7. Clean only in water, isopropanol, ethanol, Freon TF or TE (or equivalent), or Genesolve DI-15 (or equivalent).
8. Maximum tolerable component side temperature is 134°C during solder process.
