NOTE:
1. Derate power dissipation linearly 3.00 mW/C above 25C ambient.
2. Derate power dissipation linearly 6.00 mW/C above 25C case.
3. RMA flux is recommended.
4. Methanol or isopropyl alcohols are recommended as cleaning agents.
5. Soldering iron tip
1/16"
(1.6mm) minimum from housing.
6. As long as leads are not under any stress or spring tension.
7. Light source is a GaAs LED emitting light at a peak wavelength of 940 nm.
8. Figure 1 and figure 2 use light source of tungsten lamp at 2870K color temperature. A GaAs source of 3.0 mW/cm
2
is approximately
equivalent to a tungsten source, at 2870K, of 10 mW/cm
