The wide receiving angle provides relatively even reception over a large area. The sidelooking package is designed for easy PC board mounting of slotted optical switches or optical interrupt detectors. This series is mechanically and spectrally matched to the OP140 and OP240 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 1.33 mW/o C above 25 o C. (3) Light source is an unfiltered GaAs LED with a peak emission wavelength of 935 nm and a radiometric intensity level which varies less than 10% over the entire lens surface of the phototransistor being tested. (4) The knee point irradiance is defined as the irradiance required to increase IC(ON) to 50 µA. Typical Performance Curves Typical Spectral Response Schematic The phototransistor has an internal base-emitter resistor which provides protection from low level ambient lighting conditions. This feature is also useful when the media being detected is semi-transparent to infrared light in interruptive applications. Wavelength - nm Optek Technology, Inc. 1215 W.
