Descripon:
Each device in the OP265 and OP266 series is a high intensity gallium arsenide infrared eming diode (GaAIAs) that is
molded in an IR transmissive clear epoxy package with either a dome or at lens. Devices feature narrow and wide
irradiance paerns and a variety of electrical characteriscs. The small T-1 package style makes these devices ideal for
space-limited applicaons.
OP265 devices conform to the OP505 and OP535 series devices. OP266 devices conform to OP506 series devices.
Please refer to Applicaon Bullens 208 and 210 for addional design informaon and reliability (degradaon) data.
Applicaons:
Space-limited applicaons
Applicaons requiring coupling eciency
Baery-operated or voltage-limited
applicaons
Features:
T-1 (3 mm) package style
Choice of narrow or wide irradiance paern
Choice of dome or at lens
Mechanically and spectrally matched to other OPTEK devices

Notes:
1. Derate linearly 1.33 mW/°C above 25°C
2. EE(APT) is a measurement of the average apertured rediant incidence ipon a sensing
area 0.081” (2.06 mm) in diameter, perpendicular to and centered on the
mechanical axis of the lens, and 0.590” (14.99 mm) from the measurement surface.
EE(APT) is not necessarily uniform within the measured areas.
