The SMD2420 series surface mount infrared components are small ceramic packages (0.15 in x 0.10 in x 0.083 in/3.81 mm x 2.54 mm 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 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.
