PIN Sili con Pho to di ode
Type OP905
Fea tures
• Narrow receiving angle
• Linear response vs. irradiance
• Fast switching time
• T-1 package style
• Small package ideal for space limited
applications
De scrip tion
The OP905 device consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared light
wavelengths. The narrow receiving angle
provides excellent on-axis coupling.
These devices are 100% production
tested using infrared light for close
correlation with Optek’s GaAs and
GaAlAs emitters.

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering.
Max. 20 grams force may be applied to leads when soldering.
(2) Derate linearly 1.67 mW/o C above 25o C.
(3) 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
photodiode being tested.
(4) To calculate typical dark current in nA, use the formula ID = 10
ambient temperature in o C.
