Features e Flat lensed for wide acceptance angle e Easily stackable on 0.100 inch (2.54 mm) hole centers e Low cost plastic package Mechanically and spectrally matched to the OP168F and OP268F series of infrared emitting diodes Description The OP538F series consists of NPN silicon photodarlingtons mounted in flat lensed, black plastic, end looking packages. The flat sensing surface allows an acceptance half angle of 65 measured from the optical axis to the half power point. The black plastic package significantly reduces ambient light noise. These devices can be mounted on 0.100 (2.54 mm) hole centers making them an ideal low cost alternative to hermetic OP600 sensors.

Duration can be extended to 10 seconds max. when flow soldering. Maximum 20 grams force may be applied to the leads when soldering. (2) Derate linearly 1.33 mW/ C above 25 C. (3) Light source is an unfiltered GaAs LED with a peak emission wavelength of 935 nm anda radiometric intensity level which varies less than 10% over the entire lens surface of the phototransistor being tested. (4) Due to high gain of photodarlington, a load resistor should be used to avoid thermal runaways. : Typical Performance Curves Typical Spectral Response Coupling Characteristics of OP168F and OP538F 0 3.0 Ip- 20 mA f se a 2 Vee - 5 2 / \ ' 20 60 3 B18 : orl 2 B 10 & N ce 2 ~ 05 x Pp 0 0 ao 86 700i (ass St 0 02 of O08 08 1.0 DISTANCE BETWEEN LENS TIPS Inches Wavelength - nm Optek Technology, Inc. 1215 W.
