SMD2440-021

Infrared Components Ceramic Discrete Surface Mount Emitters and Detectors FEATURES • Small package size • Glass lensed optics for efficient optical coupling • Upright or inverted mounting capability • Low profile, small size for flexible layout of multiple channels and custom arrays • Compatible with automated solder processes: - IR reflow - vapor phase - solder wave - convection oven • Choice of photodiode or phototransistor detectors • IRED features high power dissipation capability • Tape and reel packaging option − pick and place machine compatible APPLICATIONS • Optical encoders for motion control • Computer peripherals • Vending and point-of-sale applications • Smoke detectors • Medical equipment SME/SMD Series The SME2470, SMD2440 and SMD2420 Series surface mount infrared components are small ceramic packages (0.15 x 0.10 x 0.083 in. / 3,81 x 2,54 x 2,1 mm) with glass lenses. The lens minimizes cross talk and often eliminates the need for apertures in non-critical applications. The low profile components may be mounted on the printed circuit board, lens up or inverted, allowing flexibility in layouts for multiple channel and custom arrays. When mounted lens down over a hole in the PC board, the lens is hidden, lowering overall package height. The SME2470 is a high intensity aluminum gallium arsenide infrared emitting diode (IRED) which can be used with either the SMD2440 phototransistor or the SMD2420 photodiode. It supplies optimum optical characteristics and efficient optical coupling. The small size and high power dissipation properties of the IRED promote PC board miniaturization and high density placement. The SMD2440 Series phototransistor’s gain characteristics make it useful for applications requiring high responsivity. The SMD2420 Series photodiode is especially useful in applications requiring linear response or high switching speed. These components are available in bulk, or on tape and reel for use with automatic placement equipment.
