PIN Silicon Photodiode

Type OP950

Features

• Wide receiving angle

• Linear response vs. irradiance

• Fast switching time

• Side-looking package ideal for space

limited applications

Description

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.
