OP140, OP145 Series
Features:
IR-transmissive plastic package
Side-looking package for space-limited applications
Wide irradiance pattern
Mechanically and spectrally matched to other OPTEK products
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, C) 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.
Applications:
Space-limited applications
PCBoard mounted slotted switch
PCBoard interrupter

Notes:
1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum of 20 grams
force may be applied to the leads when soldering.
2. Derate linearly 1.33 mW/° C above 25° C.
