Notes:

Solder time less than 5 seconds at temperature extreme.

De-rate linearly at 2.17 mW/° C above 25° C.

Light source is an unfiltered GaAs LED with a peak emission wavelength of 935nm and a radiometric intensity level which varies less than

10% over the entire lens surface of the phototransistor being tested.

To Calculate typical collector dark current in µA, use the formula ICEO = 10

(0.04Ta-3.4) where Ta is the ambient temperature in ° C.
