Derate power dissipation linearly 3.00mW/°C above 25°C ambient. 2. Derate power dissipation linearly 6.00mW/°C above 25°C case. 3. RMA flux is recommended. 4. Methanol or Isopropyl alcohols are recommended as cleaning agents. 5. Soldering iron tip ‘4e" (1.6 mm) 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 2870°K color temperature. A GaAs source of 0.05 mW/crr is approximately equivalent to a tungsten source, at 2870°K, of 0.2 mW/cnr.
