Higher power output than GaAs at equivalent LEDs
Descripꢀon:
Each device in this series, is a gallium aluminum arsenide infrared Light Emiꢂng 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
idenꢁficaꢁon 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, Plasꢀc 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 opꢁons A, B and C. The OP290 series forward
current is specified under pulse condiꢁons up to 1.5 amps, the OP291 series forward current is specified under pulse
condiꢁons up to 100 milliamps and the OP292 series forward current is specified under pulse condiꢁons 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
characterisꢁcs.
Each OP293 and OP298 series come in three electrical parameter opꢁons 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 hermeꢁc packages.
Each OP298 series come with a high irradiance output versions with four electrical parameter opꢁons AA, AB, AC and AD.
These power opꢁons are in the range of 5X greater than the A, B or C opꢁons. 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 hermeꢁc packages.
OP294 and OP299 are designed for low-current or power-limited applicaꢁons, such as baꢀery 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 conꢁnuous (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 opꢁons A, B and C. The OP295 series forward
current is specified under pulse condiꢁons up to 5 amps, the OP296 series forward current is specified under pulse
condiꢁons up to 2 amps and the OP297 series forward current is specified under pulse condiꢁons 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 characterisꢁcs.
All of these devices are spectrally and mechanically matched to the OP593 and OP598 series phototransistors.
