    Products Detail

    The OP290 series offers infrared LEDs with choices in irradiance pattern (narrow/wide), power output, and package (T-1¾, TO-18, TO-46). They feature higher power output than GaAs LEDs and are available in multiple electrical specification options (A, B, C, etc.). The series includes devices with different forward current ratings and emission angles, designed for low-cost replacement of hermetic packages. They are spectrally and mechanically matched to OP593 and OP598 phototransistors.

    Key Features

    • Irradiance pattern: narrow or wide
    • Power ranges: multiple
    • Package options: T-1¾, TO-18, TO-46
