Fast, Blue-Sensitive Silicon Photomultiplier Sensors
SensL’s B-Series low-light sensors feature industry leading PDE that extends much further into the blue part of the
spectrum using a P-on-N silicon process. For ultrafast timing applications select B-Series sensors have a uniquely
fast output, first introduced in SensL’s M-Series sensors. These fast signals can have rise times of 300ps and pulse
widths of 600ps. The B-Series is available in different sensor sizes (1mm, 3mm and 6mm) and packaged in a variety
of formats, including a 4-side tileable surface mount (SMT) package that is compatible with lead-free, reflow soldering
processes.
The B-Series sensors are based on the silicon photomultiplier concept and
form a range of high gain, single-photon sensitive, UV to visible-light sensors.
They have performance characteristics similar to a conventional PMT, while
benefiting from the practical advantages of solid-state technology: low
operating voltage, excellent temperature stability, robustness, compactness,
output uniformity, and low cost. For more information on the B-Series devices
please refer to the website, www.sensl.com.

FAST OUTPUT SIGNALS
The oscilloscope graphs below show examples of measured waveforms from the fast output of 1mm, 3mm and 6mm sensors
mounted on the SensL SMA product boards; the MicroFB-SMA-10035, MicroFB-SMA-30035 and MicroFB-SMA-60035. All
measurements are obtained using a 2.5GHz bandwidth oscilloscope and 45ps pulses from a 405nm laser at 100kHz. No amplifier
was used, and the output of the SMA product boards was directly connected to the oscilloscope using a 1m long, 50Ω coaxial cable.

B-SERIES EVALUATION BOARD OPTIONS
SMA BIASING BOARD (MicroFB-SMA-XXXXX)
The MicroFB-SMA is a simple board designed to allow evaluation of the MicroFB SMT range of SiPM
sensors. The board has SMA connectors for connecting the bias voltage, standard output from the
anode and the fast output signal. The biasing and output line is laid out in such a way as to preserve
the fast timing characteristics of the sensor.
The MicroFB-SMA is recommended for users who require a plug-and-play set-up to quickly evaluate
FB-series SMT sensors with optimum timing performance. The board also allows the standard
output from the anode to be observed at the same time as the fast output. The outputs can be
connected directly to the oscilloscope or measurement device. The table below lists the SMA board
connections.

PIN ADAPTER (MicroFB-SMTPA-XXXXX)
The SMT Pin Adapter board (SMTPA) is a small PCB board that houses the SMT sensor and has
through-hole pins to allow its use with standard sockets or probe clips. This product is useful for
those needing a quick way to evaluate the SMT package without the need for specialist surfacemount soldering. While this is a ‘quick fix’ suitable for many evaluations, it should be noted that
the timing performance from this board will not be optimized and if the best possible timing
performance is required, the MicroFB-SMA-XXXXX is recommended.

TILING OF THE SMT PACKAGE
SensL has developed a market-leading, custom SMT package for the B-series sensors. It is a compact, leadless, chip-scale package
that is compatible with lead-free, reflow soldering processes. A clear encapsulant is used for optimal coupling to scintillators or fibre optic
elements.

B-Series Fast, Blue-Sensitive Silicon Photomultiplier Sensors
DATASHEET
The dead-space between the sensor chip and the edge of the package has been minimized resulting in a package that can be tiled on
4 sides. This allows multiple devices to be configured into unique layouts for a wide range of custom applications. Two-dimensional tiling
examples are illustrated for the 1mm, 3mm and 6mm packages. The distance between active areas is typically 1.2mm when tiled, but actual
alignment and placement tolerances will depend on the accuracy of the user’s assembly process. A Technical Note is available that gives
advice on creating arrays of the SMT sensors.
