Broadcom AFBR-S4N44P164M 4×4 NUV-MT Photo Multiplier Array

The Broadcom/Avago AFBR-S4N44P164M 4×4 NUV-MT Photo Multiplier Array features encapsulation achieving excellent mechanical stability and robustness. A clear epoxy mold compound realizes these features, 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.

The array is ideal for the detection of low-level pulsed light sources, especially for the detection of Cherenkov or scintillation light from the most common organic (plastic) and inorganic scintillator materials (for example, LSO, LYSO, BGO, NaI, CsI, BaF, LaBr3). Additionally, the device is lead-free and compliant with RoHS.


  • 4×4 SiPM array
  • Array size 16.00mm × 16.00mm
  • High PDE (63% at 420nm)
  • Excellent SPTR and CRT
  • Excellent uniformity of breakdown voltage
  • Excellent uniformity of gain
  • 4-side tileable, with high fill factors
  • Cell pitch 40μm
  • Highly transparent epoxy protection layer
  • Operating temperature range from –20°C to +50°C
  • RoHS, CFM, and REACH compliant


  • X-ray and gamma-ray detection
  • Nuclear medicine
  • Positron emission tomography
  • Safety and security
  • Physics experiments
  • Cherenkov detection
