BROADCOM AFBR-S4N44P014M Silicon Photomultiplier, 3.72mm Ã� 3.62mm, 40µm/8334Microcells, 420nm, SMD, 5 Pin

AFBR-S4N44P014M is a single-channel silicon photo multiplier (SiPM) used for ultra-sensitive precision measurements of single photons. This SiPM is based on the NUV-MT technology, which combines best-in-class photodetection efficiency (PDE) with decreased dark count rate and reduced crosstalk when compared to the NUV-HD technology. The SPAD pitch is 40μm. The encapsulation for good mechanical stability and robustness is realized by an epoxy clear mould compound, which is highly transparent down to UV wavelengths, resulting in a broad response in the visible light spectrum with high sensitivity toward the blue and near-UV region of the light spectrum. It is used in applications such as X-ray and gamma-ray detection, nuclear medicine, positron emission tomography, photon counting X-ray, safety and security, physics experiments, cherenkov detection.
