Plastic Infrared Emitting Diode
OP165, OP166 Series
Features:
• T-1 (3 mm) package style
• Choice of narrow or wide irradiance pattern
• 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 emitting diode (GaAIAs)
that is molded in an IR transmissive clear epoxy package with either a dome or flat lens. Devices feature narrow
and wide irradiance patterns and a variety of electrical characteristics. The small T-1 package style makes these
devices ideal for space-limited applications.
OP165 and OP166 devices are m echanically and spectrally matched to the OP505 and OP535 series devices.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
Applications:
• Space-limited applications
• Applications requiring coupling
efficiency
• Battery-operated or voltage-limited
applications

mm) from the measurement surface. EE(APT) is not necessarily
uniform within the measured areas.
