Glossary
1)
Radiant intensity: Measured at a solid angle of Ω = 0.01 sr
2)
Reverse Operation: Reverse Operation of 10 hours is permissible in total. Continuous reverse opera-
tion is not allowed.
3)
Total radiant ux: Measured with integrating sphere.
4)
Thermal resistance: junction - soldering point, of the device only, mounted on an ideal heatsink (e.g.
metal block)
5)
Thermal resistance: junction ‐ ambient, mounted on PC‐board (FR4), padsize 16 mm² each
6)
Typical Values: Due to the special conditions of the manufacturing processes of semiconductor devic-
es, the typical data or calculated correlations of technical parameters can only reect statistical gures.
These do not necessarily correspond to the actual parameters of each single product, which could dif-
fer from the typical data and calculated correlations or the typical characteristic line. If requested, e.g.
because of technical improvements, these typ. data will be changed without any further notice.
7)
Testing temperature: T
A
= 25°C
8)
Tolerance of Measure: Unless otherwise noted in drawing, tolerances are specied with ±0.1 and
dimensions are specied in mm.
9)
Tape and Reel: All dimensions and tolerances are specied acc. IEC 60286-3 and specied in mm.
