PIN Silicon Photodiode
Type OP955
Features
• Wide receiving angle
• Linear response vs. irradiance
• Fast switching time
• Side-looking package ideal for space
limited applications
Description
The OP955 devices consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared
wavelengths. The wide receiving angle
provides relatively even reception over a
large area. The side-looking package is
designed for easy PC board mounting.
The lensing effect of the package allows
an acceptance half angle of 45^o
measured from the optical axis to the half
power point. 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 25^o 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.
