at f = 1 kHz, DF = 6.7%.
2. Derate linearly as shown in Figure 4.
3. The transient peak current is the maximum non-recurring peak current the device can withstand without damaging the LED die and wire bonds.
It is not recommended that the device be operated at peak currents beyond the Absolute Maximum Peak Forward Current.
