Plastic Infrared Emitting Diode
OP140 Series, OP145C
Obsolete (OP145A)
Features:
• IR-transmissive plasꢁc package
• Side-looking package for space-limited applicaꢁons
• Wide irradiance paꢀern
• Mechanically and spectrally matched to other OPTEK products
Description:
Each device in this series is a high intensity gallium arsenide infrared emiꢂng diode that is suited for use as a PCBoard
mounted sloꢀed switch or an easy mount PCBoard interrupter.
Each OP140 (A, B, C, D) and OP145C device is a domed-lens 935 nm diode that is molded in an IR-transmissive plasꢁc 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.
