AFBR-S4N44C013

The Broadcom® AFBR-S4N44C013 is a silicon photo multiplier (SiPM) array used for ultra-sensitive precision measurement of single photons.The active area is 3.72 × 3.72 mm2. High packing density of the single chip is achieved using through-silicon-via (TSV) technology. Larger areas can be covered by tiling multiple AFBR-S4N44C013 arrays almost without any edge losses. The passivation layer is made by a glass highly transparent down to UV wavelengths, resulting in a broad response in the visible light spectrum with high sensitivity towards blue- and near-UV region of the light spectrum.
