Description
The OP954 device consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared light
wavelengths. The very wide receiving
angle provides relatively even reception
over a large area. The side-looking
package is designed for easy PC board
mounting. 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 µA, use the formula ID = 10(0.042 TA-1.5) where TA is
ambient temperature in o C.
