ROHM High-Performance Infrared LEDs Are Ideal for Proximity Sensing Surface mount, high-output Infrared LEDs feature industry's lowest profile; 850/870 nm peak output improves sensitivity; 66% lower power use important in portable devices

SAN DIEGO, Jan. 26, 2011 /PRNewswire/ -- 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.

The SIM-030/031ST, the smaller of the two devices, has a 2.3 mm x 1.95 mm footprint and a height of just 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 mm x 2.25 mm x 1.6 mm) provides 40 mW/sr, typical emission strength.  

Field Application Engineer for ROHM Semiconductor, AviElmaleh, said, "The combination of ROHM's advanced process technology and packaging has resulted in a superior product for space-constrained proximity sensing. The SIM-030/031ST is the perfect choice for power saving in cell phones, turning off the display when the device is closer to the ear."

The ROHM SIM-030/031ST and SIM-040/041ST are the latest additions to the ROHM Optical Sensors Series of emitters, receivers, photointerrupters, tilt sensors, IrDA modules and remote control modules.

Pricing(small OEM qty.):US$0.75(SIM-030ST)
