Carrollton, TX: Providing military systems engineers the ability to achieve high brightness color illumination and indication with well-defined patterns, TT 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. Unlike commercial LEDs, these devices are designed to function in extreme conditions that are typically found in defense electronics, military vehicle lighting and harsh industrial applications.

"As more lighting applications in military electronics are being implemented with solid state light sources, we recognized the need for a high-reliability, ruggedized version of our color LEDs that incorporated built-in ESD protection," said Rodney Bailey, vice president of optoelectronic component solutions for TT electronics OPTEK Technology. "The OVM4x Series combines our high-brightness LEDs with a proven hermetically sealed TO-46 package that is specifically designed to withstand the severe levels of mechanical, environmental and electrical stress typical in field-deployed military electronics systems."

According to Bailey, the OVM4xTX and OVM4xTXV LEDs are processed to OPTEK's 100% screening and QC program patterned after MIL-PRF-19500 standards, with Group A and B testing performed on each lot. Group C testing is performed every six months to ensure reliability.

Color intensity and dominant wavelength specifications for the OVM4x Series LEDs are as follows:
  • OVM4BTX/TXV blue LEDs are made of indium gallium nitride (InGaN) with typical luminous intensity of 2260mcd and dominant wavelength from 460 - 470nm at IF=20mA. Forward voltage is rated from 2.60V (typical) to 2.95V (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=20mA. Forward voltage is rated from 2.60 (typical) to 2.95V (max.)

  • OVM4RTX/TXV red LEDs are made of aluminum indium gallium phosphide (AlInGaP) with typical luminous intensity of 3330mcd and dominant wavelength from 619 - 629nm at IF=20mA. Forward voltage is rated from 1.8 (typical) to 2.15V (max.)

  • OVM4YTX/TXV yellow LEDs are made of aluminum indium gallium phosphide (AlInGaP) with typical luminous intensity of 2010mcd and dominant wavelength from 584 - 594nm at IF=20mA. Forward voltage is rated from 1.8 (typical) to 2.15V (max.)

    All LEDs in the OVM4x series exhibit continuous forward current of 100 mA, with a peak forward current rating of 1.6A (@10% duty cycle, 1KHz). Power dissipation is 370 mW; with a current linearity vs. ambient temperature rating of -0.2mA/°C. Operating temperature range is from -55°C to +100°C.

    Packaged with a clear glass lens, the LEDs feature a viewing angle of 18°.

    Typical pricing for the OVM4x Series LEDs is $10.08/ea in quantities of 1,000, the OVM4xTX Series is $14.56/ea in quantities of 1,000 and the OVM4xTXV Series is $14.80/ea in quantities of 1,000. Lead times will vary due to testing requirements. If stock is not available the OVM4x Series lead time is from 10 to 12 weeks, the OVM4xTX lead time is from 18-20 weeks and the OVM4xTXV series lead time is from 18-20 weeks.
