PIN Silicon Photodiode

Type OP954

Features

? Very wide receiving angle

? Linear response vs. irradiance

? Fast switching time

? Side-looking package ideal for space

limited applications

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

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.

(4) To calculate typical dark current in μ A, use the formula I D = 10 (0.042 TA-1.5) where T A is

ambient temperature in o C.
