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 an 875 nm 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). Plastic Package TO-18 or TO-46 devices

include: OP293 and OP298 (A, B, C, AA, AB, AC, 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

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 silver-

copper lead frame offers excellent thermal characteristics. These devices are UL recognized, File No. S2047.

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.
