Features:
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, 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
OP297FAB has a reversed polarity from the OP297A, B or C. 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.
