Type OP950
Fea tures
• Wide receiving angle
• Linear response vs. irradiance
• Fast switching time
• Side-looking package ideal for space
limited applications
De scrip tion
The OP950 device consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared light
wavelengths. The wide receiving angle
provides relatively even reception over a
large area. The side-looking package is
designed for easy PC board mounting.
This photodiode is mechanically and
spectrally matched to Optek’s GaAs and
GaAlAs series of infrared emitting
diodes.

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 µA, use the formula ID = 10
ambient temperature in o C.
