Notes:

1. Derate linerally as shown in Figure 4.

2. Refer to Figure 5 to establish pulsed operating conditions.

3. The transient peak current is the maximum non-recurring peak current the device can

withstand without damaging the LED die and wire bonds.

4. Drive currents between 5 mA and 30 mA are recommended for best long term

performance.

5. Operation at currents below 5 mA is not recommended, please contact your Hewlett-

Packard sales representative.
