1. See Figure 10 (High Efficiency Red), 15 (Yellow), or 20 (Green) to establish pulsed operating conditions.
2. For High Efficiency Red and Green Series, derate linearly from 50°C at 0.5 mA/°C. For Red and Yellow Series, derate linearly from 50°C at 0.2 mA/°C.
3. For High Efficiency Red and Green Series, derate power linearly from 25°C at 1.8 mW/°C. For Red and Yellow Series, derate power linearly from 50°C at
1.6 mW/°C.
4. The transient peak current is the maximum non-recurring peak current that can be applied to the device without damaging the LED die and wirebond. It
is not recommended that the device be operated at peak current beyond the peak forward current listed in the Absolute Maximum Ratings.
