Plastic Infrared Emitting Diode OP290 Series
●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, exceptfor 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: OP293and OP298 (A, B, C, AA, AB, AC, AD).
●Each OP290, OP291 and OP292series come in three electrical parameters options A, B and C. The OP290 series forward current is specified underpulse conditions up to 1.5 amps, the OP291series forward current is specified under pulse conditions up to 100 milliamps and the OP292series 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 OP293and OP298series 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 OP298series come with a high irradiance output versionswith four electrical parameter options AA, AB, AC and AD. These power options are in the range of 5Xgreater than the A, B or C options. The OP298 series has an included emission angle of 25°. The Cathode Lead length is0.06” (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.
●Features:
●• Choice of narrow or wide irradiance pattern
