OP290 Datasheet | TT Electronics

Features : - Choice of narrow or wide irradiance pattern - Choice of power ranges - Choice of T-1¾, TO-18 or TO-46 package - Higher power output than Ga As at equivalent LEDs Description : Each device in this series, is a gallium aluminum arsenide infrared Light Emitting Diode (LED) that is molded in an IRtransmissive package with a wavelength centered at 890 nm, which closely matches the spectral response of silicon phototransistors, except for OP298AA, which has an 875 nm center wavelength. For identification purposes, each LED anode lead is longer than the cathode lead. Package T-1¾ devices include: OP290 (A, B, C), OP291A, OP292A, OP294 (A, B, C), OP295 (A, B), OP296 (A, B), OP297A, OP299 (A, B, C) and OP297FAB, Plastic Package TO-18 or TO-46 devices include: OP293 (A, B) and OP298 (A, B, C, AA). The OP290 series forward current is specified under pulse conditions up to 1.5 amps, the OP291A forward current is specified under pulse conditions up to 100 milliamps and the OP292A 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. The OP293 (A, B) have an included emission angle of 60° while the OP298 (A, B, C) have an included emission angle of 25°. The Cathode Lead length is 0.06” (1.52 mm) shorter than the Anode Lead. These devices, which e in a variety of power ranges offering a low cost replacement for TO-18 or TO-46 hermetic packages. The OP298AA is a high irradiance output version with an included emission angle of 25°. The Cathode Lead length is 0.06” (1.52 mm) shorter than the Anode Lead. These devices, which e 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...
