OPTEK Technology (Carrollton, TX) has developed a series of color LEDs processed to meet MIL-PRF-19500-level TX and TXV specifications and help military systems engineers achieve high brightness, color illumination, and indication with well-defined patterns. Designated the OVM4x series, the visible blue, green, red, and yellow LEDs have a hermetically sealed TO-46 package with built-in ESD protection. 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, 1 KHz). The LEDs have a power dissipation of 370 mW and a current linearity vs. ambient temperature rating of -0.2mA/°C. Packaged with a clear glass lens, the LEDs also feature a viewing angle of 18° and an operating temperature range from -55°C to +100°C.
