* The BPW38 is a silicon photodarlington mounted in narrow angle TO-18 package. 1. Derate power dissipation linearly 3.00 mW/°C above 25°C ambient. 2. Derate power dissipation linearly 6.00 mW/°C above 25°C 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.
BPW41N is a high speed and high sensitive PIN photodiode in a flat side view plastic package.
The epoxy package itself is an IR filter, spectrally matched to GaAs or GaAs on GaAlAs IR emitters ( p = 950 nm).
The large active area combined with a flat case gives a high sensitivity at a wide viewing angle.
