J-Series Silicon Photomultiplier (SiPM) Sensors

onsemi J-Series Silicon Photomultiplier (SiPM) Sensors have been optimised 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% and their sensitivity extends down into the UV region. 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. J-Series sensors also feature onsemi's unique fast output for fast timing capability.
