Visible Color LEDs Suit High-Reliability Military and Harsh-Environment Industrial Apps

Thu, 11/04/2010 - 12:10pm
LEDs for mil-industTT electronics OPTEK Technology has developed a series of high-reliability, high-sensitivity color LEDs processed to MIL-PRF-19500-level TX and TXV specifications. Designated the OVM4x Series, the visible LEDs feature hermetically sealed TO-46 package with built-in ESD protection, and are available in blue, green, red and yellow. These devices are designed to function in extreme conditions that are typically found in defense electronics, military vehicle lighting and harsh industrial applications. OVM4BTX/TXV blue LEDs are made of indium gallium nitride (InGaN) with typical luminous intensity of 2260 mcd and dominant wavelength from 460 to 470nm at IF = 20 mA. Forward voltage is rated from 2.60 V (typical) to 2.95 V (max.). OVM4GTX/TXV green LEDs are made of indium gallium nitride (InGaN) with typical luminous intensity of 6520mcd and dominant wavelength from 520 – 540nm at IF = 20 mA. Forward voltage is rated from 2.60 V (typical) to 2.95 V (max.). OVM4RTX/TXV red LEDs are made of aluminum indium gallium phosphide (AlInGaP) with typical luminous intensity of 3330 mcd and dominant wavelength from 619 nm to 629 nm at IF = 20 mA. Forward voltage is rated from 1.8 V (typical) to 2.15 V (max.). OVM4YTX/TXV yellow LEDs are made of aluminum indium gallium phosphide (AlInGaP) with typical luminous intensity of 2010 mcd and dominant wavelength from 584 to– 594 nm at I F= 20mA. Forward voltage is rated from 1.8 V (typical) to 2.15 V (max.). All LEDs in the series exhibit continuous forward current of 100 mA, with a peak forward current rating of 1.6A (at 10 percent duty cycle, 1 kHz). Power dissipation is 370 mW; with a current linearity versus ambient temperature rating of -0.2 mA/°C. The operating temperature range is from -55°C to +100°C. Packaged with a clear glass lens, the LEDs feature a viewing angle of 18°.
