ROHM High-Performance Infrared LEDs

A new series of high-performance infrared LEDs ideally suited for proximity sensor applications is now available from ROHM Semiconductor. The SIM-030/031ST and SIM-040/041ST surface-mount IR LEDs feature breakthrough IR wavelength technology providing peak output of 850/870 nm, compared to 950 nm for comparable devices. 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%. In addition, the small package footprint and low-profile further enhance their application in cell phones and other portable devices.
