SPEC NO: DSAA6237 REV NO: V.6 DATE:MAR/20/2005 APPROVED: J. Lu CHECKED: Allen Liu DRAWN:B.H.LI PAGE: 2 OF 3 L-34SF4C Remarks: If special sorting is required (e.g. binning based on forward voltage or radiant intensity), the typical accuracy of the sorting process is as follows: 1. Radiant Intensity: +/-15% 2. Forward Voltage: +/-0.1V Note: Accuracy may depend on the sorting parameters. SPEC NO: DSAA6237 REV NO: V.6 DATE:MAR/20/2005 APPROVED: J.
