With the T-Midled SFH 4140, a surface-mountable infrared LED can be sunk in a pc board for the first time. Only 0.6mm of the T-shaped transmitter extend above and below the board.
The component size is only 3.1mm x 1.5mm x 1.5mm, thus it takes up only 4.6mm² of board space. Thanks to an integrated reflector, a powerful focused beam is emitted to the side in a beam angle of +/-25 degrees. With a typical radiant intensity of 100mA, the SFH 4140 produces 50mW/sr (per steradiant) and achieves a wavelength of 940nm.
The T-Midled SFH 4140 was designed for home entertainment electronics: If a smartphone or tablet is equipped with the appropriate infrared transmitter diode, the diode can be controlled via suitable app and thus be turned into an universal remote control.
