Plastic Infrared Emitting Diode
OP265, OP266 Series
(A, B, C, D, W)
Features:
T-1 (3 mm) package style
Choice of narrow or wide irradiance pattern
Choice of dome or flat lens
Mechanically and spectrally matched to other OPTEK devices
Higher power output than GaAs at equivalent drive currents
890 nm diodes
Description:
Each device in the
OP265
and
OP266
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.
OP265 devices conform to the OP505 and OP535 series devices. OP266 devices conform to OP506 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

E(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. E
E(APT)
is not necessarily
uniform within the measured areas.
