Description
The OP750 series devices consist of an
NPN silicon phototransistor molded in a
clear epoxy package. 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.

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.
