product description

C30927 series of quadrant Si Avalanche Photodiode and the C30985E multi-element APD array

utilize the double-diffused “reach-through” structure. This structure provides ultra high sensitivity

at 400-1000 nm.

The C30927 quadrant structure has a common avalanche junction, with separation of the quadrants

achieved by segmentation of the light entry p+ surface opposite the junction. With this design, there

is no dead space between the elements and therefore no loss of response at boresight.

The C30927EH-01, -02 and -03 are optimized for use at wavelengths of 1060, 900, and 800 nm re-

spectively. Each device type will provide high responsivity and excellent performance when operated

within about 50 nm of the specified wavelength.

The C30985E is a 25 element monolithic linear APD array having a high inter-electrode resistance

with a 75 μm dead space between the elements. Packages have a common ground and bias with a

separate lead for each element output.
