Avalanche Photodiode APD Arrays & Quadrants

C30927 Series: Number of Elements 4; Photo Sensitive Diameter 1.5 mm; Responsivity 15-62 A/W; Capacitance 1 pF; NEP 9-16 fW/√Hz; Spectral Noise Current per Element 0.5 pA/√Hz

Excelitas’ C30927 family of avalanche photodiode (APD) arrays and quadrants utilize the double-diffused “reach-through“ structure. This structure provides ultra-high sensitivity at 400 nm to 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 APD arrays and quadrants are optimized for use at wavelengths of 1060, 900, and 800 nm respectively. 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 silicon avalanche photodiode (Si APD) consisting of a double diffused “reach-through” structure.

The standard versions of the Excelitas C30737 silicon APD array series are available with 16 or 64 elements and provide high responsivity between 500 nm and 1000nm. The standard versions are available either in a compact surface-mount “top-looking” leadless package (C30737MA) or in a BGA type “top-looking” package (C30737GA).

Both packages are ideally suited for high volume, cost-effective applications where a high gain APD is required. The leadless SMD and BGA packaged parts are RoHS-compliant and suitable for reflow soldering.

The C30737MH series of LLC SMD packaged EPI APDs has the smallest footprint SMD packages.

The C30737GA-02-64-90 silicon avalanche photodiode array (Si APD array) provides high responsivity between 500 nm and 1000 nm and is available in a BGA-type “top-looking” package. The C30737GA is ideally suited for high volume, cost-effective applications where a high gain APD is required. Its leadless BGA package is RoHS-compliant and suitable for reflow soldering.
