Infrared LEDs

altA set of surface-mount, high-output infrared LEDs from ROHM Semiconductor (San Diego, CA) can be used in proximity sensor applications. The SIM-030/031ST and SIM-040/041ST surface-mount IR LEDs feature IR wavelength technology providing peak output of 850/870 nm. The 850/870 nm level is much closer to the peak wave sensitivity of phototransistors (sensors), thus achieving higher efficiency proximity sensing and energy savings of up to 66%. The SIM-030/031ST, the smaller of the two devices, has a 2.3 × 1.95 mm footprint and a height of 0.9 mm. With a forward current (IF) of 100 mA, the device delivers typical emission strength of 30 mW/sr (milliwatts per steradian). The slightly larger SIM-040/041ST (3.1 × 2.25 × 1.6 mm) provides 40 mW/sr, a typical emission strength.
