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.
