Plastic Infrared Emitting Diode

OP140, OP145 Series

Description:

Each device in this series is a high intensity gallium arsenide infrared emitting diode that is suited for use as a

PCBoard mounted slotted switch or an easy mount PCBoard interrupter.

Each OP140 (A, B, C, D) and OP145 (A, B, C, D) device is a domed-lens 935 nm diode that is molded in an IR-

transmissive plastic side-looking package.

OP140 is mechanically and spectrally matched to the OP550 series of phototransistors and the OP560 series of

photodarlingtons. OP145 is mechanically and spectrally matched to the OP555 and OP565 series devices.

Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
