SensL have three different silicon series, each of which which combines high photon detection efficiency (PDE) with low dark count rate, but with other varying characteristics that are suited to specific applications. The different silicon series can be summarized as follows:
- C-Series – General purpose, blue sensitive, lowest cross-talk and noise.
- J-Series – Blue sensitive, highest PDE, optimized for fast timing applications, high-fill factor package.
- R-Series – General purpose red sensitive, highest PDE, optimized for fast timing applications.
The full datasheets for each silicon series are found on the individual product pages. The table below summarizes some of the main characteristics for each silicon series, based on a 35um microcell.
|Sensitivity range||300nm - 800nm||300nm - 800nm||380nm - 1100nm|
|Breakdown voltage (Typical)||24.5V||24.5V||24.5V|
|Recommended operating voltage||Vbr + 5V||Vbr + 5V||Vbr + 5V|
|Dark count rate (typical)||60 kHz/mm2||70 kHz/mm2||70 kHz/mm2|
|Microcell recharge time constant (RC)||82ns||49ns||49ns|
|Fast output terminal||yes||yes||yes|
The range of package types are summarized below, which in combination with the ‘Silicon Family’ table can aid the user in choosing the ideal SensL product for their application.
