OP266AA SERIES

Features:

 T-1 (3 mm) package style

 Narrow irradiance pattern

 Dome lens

 Higher power output than GaAs at equivalent drive currents

 850 nm diode

Description:

Each device in the OP266AA series is a high intensity gallium aluminum arsenide infrared emitting diode (GaAIAs) that is

molded in an IR transmissive clear or amber-tinted epoxy package with a dome lens. Devices feature a narrow source

irradiance pattern and a variety of electrical characteristics. The small T-1 package style makes these devices ideal for space

-limited applications.

These devices are mechanically and spectrally matched to other OPTEK products as follows:

The OP266AA family conform to the OP506 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

NOTES:

1. Outside discrete shell is polysulfone CLEAR.

2. This LED is built with a GaAlAs chip.

3. Max allowable epoxy miniscus is 0.030”.

4. For identification purposes, Cathode lead is .065” ± .035” longer

than the anode lead.

To avoid stress cracking, we suggest using

ND Industries’ Vibra-Tite for thread-locking.

Vibra-Tite evaporates fast without causing structural failure in

OPTEK'S molded plastics.

Notes:

1. RMA flux is recommended. Duration can be extended to 10 second maximum when flow soldering. A maximum of 20 grams force may be

applied to the leads when soldering.

2. Derate linearly at 1.33 mW/° C above 25° C.

3. EE(APT) is a measurement of the average apertured radiant incidence upon 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 area.
