J-Series Silicon Photomultiplier (SiPM) Sensors

onsemi J-Series Silicon Photomultiplier (SiPM) Sensors have been optimized for high-performance timing applications, such as ToF-PET (time of flight positron emission tomography). Due to increased microcell density, J-Series sensors can achieve a photon detection efficiency (PDE) of 50%, with sensitivity extending down into the UV. These sensors feature industry-leading low dark count rates of 50kHz/mm² and because the sensors are created using a high-volume CMOS silicon process, they feature an exceptional breakdown voltage uniformity of ±250mV. The J-Series sensors are available in 3mm, 4mm, and 6mm sizes packaged in a TSV chip-scale package that is compatible with industry-standard, lead-free, reflow soldering processes. onsemi J-Series Silicon Photomultiplier (SiPM) Sensors also feature onsemi's unique fast output for fast timing capability.
