Released in October 2015 SensL's J-series SiPMs have been optimised for high-performance timing applications such as ToF-PET whilst the Through Silicon Via (TSV) package is fully MRI compatible making them the ideal choice for combined MR-PET systems.
J-Series sensors achieve dramatically reduced standard-mode rise times of sub-300ps whilst recovery times are now <50ns (RC time constant). They also feature SensL’s patented fast-mode output which is improved over the C-Series equivalent with world-leading Coincidence Resolved Time performance of sub-160ps.
SensL's ultra-low Dark Count Rate is maintained at 35kHz/mm² (2.5V overbias) along with low Crosstalk/After-Pulsing and exceptional breakdown voltage uniformity of ±250mV.
Due to increased microcell density, peak PDE of >50% at 420nm is achieved whilst the glass TSV package enables significantly increased sensitivity far into the UV with cut-off at <250nm.
J-Series SiPMs are available in 3.08mm and 6.07mm active area sizes packaged in a TSV chip scale package that is compatible with industry standard, lead-free, reflow soldering processes. Package footprints of just 3.16mm and 6.13mm mean that J-Series SiPMs can be tiled in 2D arrays with extremely high geometric fill-factors - approaching 95% for the larger device.
J-Series SiPMs are high performance devices and so are only expected to be used in applications demanding their superior specification - if you are unsure as to whether J-Series is the best solution line for your application we recommend you review SensL's product selection guide and White Paper "How to evaluate and compare SiPMs".
