Description:

Each device in this series, is a gallium aluminum arsenide infrared Light Emitting Diode (LED) that is molded in an IR-

transmissive package with a wavelength centered at 890 nm, which closely matches the spectral response of silicon

phototransistors, except for OP298 (AA, AB, AC, AD), which has either an 850 nm or 875 nm center wavelength. For

identification purposes, each LED anode lead is longer than the cathode lead. Package T-1¾ devices include: OP290,

OP291, OP292, OP294, OP295, OP296, OP297, OP299 (A, B, C) and OP297FAB, Plastic Package TO-18 or TO-46 devices

include: OP293 and OP298 (A, B, C, AA, AD).

Each OP290, OP291 and OP292 series come in three electrical parameters options A, B and C. The OP290 series forward

current is specified under pulse conditions up to 1.5 amps, the OP291 series forward current is specified under pulse

conditions up to 100 milliamps and the OP292 series forward current is specified under pulse conditions up to 1 amp. The

Cathode Lead length is 0.06” (1.52 mm) shorter than the Anode Lead. The silver-copper lead frame offers excellent thermal

characteristics.

Each OP293 and OP298 series come in three electrical parameter options A, B and C. The OP293 series has an included

emission angle of 60° while the OP298 series has an included emission angle of 25°. The Cathode Lead length is 0.06” (1.52

mm) shorter than the Anode Lead. These devices, which come in a variety of power ranges offering a low cost replacement

for TO-18 or TO-46 hermetic packages.

Each OP298 series come with a high irradiance output versions with four electrical parameter options AA, AB, AC and AD.

These power options are in the range of 5X greater than the A, B or C options. The OP298 series has an included emission

angle of 25°. The Cathode Lead length is 0.06” (1.52 mm) shorter than the Anode Lead. These devices, which come in a

variety of power ranges offering a low cost replacement for TO-18 or

TO-46 hermetic packages.

OP294 and OP299 are designed for low-current or power-limited applications, such as battery supplies. They are similar to

the OP290 and OP295, but use a smaller chip that increases output efficiency at low current levels by increasing current

density. Light output can be maximized with continuous (D.C.) forward current up to 100 mA or with pulsed forward

current up to 750 mA. The Cathode Lead length is 0.06” (1.52 mm) shorter than the Anode Lead.

Each OP295, OP296 and OP297 series come in three electrical parameters options A, B and C. The OP295 series forward

current is specified under pulse conditions up to 5 amps, the OP296 series forward current is specified under pulse

conditions up to 2 amps and the OP297 series forward current is specified under pulse conditions up to 1 amp. The Cathode

Lead length is 0.06” (1.52 mm) shorter than the Anode Lead. The OP297FAB has a reversed polarity from the OP297A, B.

The silver-copper lead frame offers excellent thermal characteristics.

All of these devices are spectrally and mechanically matched to the OP593 and OP598 series phototransistors.

Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
