The Broadcom® AFBR-S4P0102L3R is a silicon photomultiplier (SiPM) that is optimized for fast photon counting and time-stamping in the near-infrared region of the electromagnetic spectrum. It combines high photodetection efficiency, low correlated noise, and steep slew rates with a wide dynamic range due to the small cell pitch and the fast recharge time.

The active region is divided into two equal and independent elements, which can be read out independently or connected together to achieve an overall photosensitive area of 1×1 mm2. This feature enables a higher degree of flexibility for the design of the readout system.

The silicon chip is encapsulated within a robust molded lead frame package through a resin compound that is highly transparent to red and infrared wavelengths, making the AFBR-S4P0102L3R SiPM best suited for LiDAR and direct time-of-flight (dToF) applications.
