Plastic Infrared Emitting Diode
OP165 Series, OP166A, OP166B
Obsolete (OP166W)
Features:
• T-1 (3 mm) package style
• Choice of narrow or wide irradiance paꢁern
• Choice of dome lens or flat lens
• Mechanically and spectrally matched to other OPTEK devices
• Higher power output than GaAs at equivalent drive currents
• 935 nm diode
Description:
Each device in the OP165 and OP166 series is a high intensity gallium arsenide infrared emiꢂng diode (GaAs) that is molded
in an IR transmissive clear epoxy package with either a dome or flat lens. Devices feature narrow and wide irradiance
paꢁerns and a variety of electrical characterisꢀcs. The small T-1 package style makes these devices ideal for space-limited
applicaꢀons.
OP165 and OP166 devices are mechanically and spectrally matched to the OP505 and OP535 series devices.
Please refer to Applicaꢀon Bulleꢀns 208 and 210 for addiꢀonal design informaꢀon and reliability (degradaꢀon) data.
Applications:
• Space-limited applicaꢀons
• Applicaꢀons requiring coupling efficiency
• Baꢁery-operated or voltage-limited applicaꢀons
