OPTEK OP236TX High reliability hermetic infrared emitting diode Datasheet

High Reliability Hermetic Infrared Emitting Diode
OP235, OP236 (TX, TXV)
Features:
• TO-46 hermetically sealed package with lens
• Twice the power output of GaAs at same drive current
• Characterized to define infrared energy along mechanical axis of
device
• Narrow beam angle
• Processed to MIL-PRF-19500.
Description:
Each device in this series is a gallium aluminum arsenide (GaAIAs) infrared emitting diode, mounted in a hermetic
metal TO-46 housing with 0.50” (12.70 mm) leads. The gallium aluminum arsenide feature provides a higher
radiated output than gallium arsenide at the same forward current, while the 890 nm wavelength closely matches
the spectral response of silicon phototransistors. Devices have lens cans that provide an 18° beam angle
between half power points, which facilitates the easy design of beam interrupt applications with the OP804 and
OP805 series of high reliability phototransistors.
TX and TXV devices are processed to OPTEK’s military screening program patterned after MIL-PRF-19500. After
100% screening, Group A and B are performed on every lot and a Group C test is performed every six months.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.

Notes:
1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
2. Derate linearly 2.00 mW/° C above 25° C.
3. EE(APT) is a measurement of the average radiant intensity within the cone formed by the measurement surface, a radius of
1.429” (36.30 mm) measured from the lens side of the tab to the sensing surface and a sensing surface of 0.250” (6.35 mm) in
diameter forming a 10° cone. EE(APT) is not necessarily uniform within the measured area.
