ON Semi – Silicon Photomultiplier RB-Series

ON Semi – Silicon Photomultiplier RB-Series


ON Semi’s RB Series of red-enhanced second generation Silicon Photomultipliers (SiPM) with high responsivity at a low bias voltage.

MicroRB−Series sensors are the second release of Silicon Photo− multipliers (SiPM) from ON Semiconductor’s R-Series range. These sensors provide further sensitivity improvements in the red and NIR region of the electromagnetic spectrum. All R-Series SiPM sensors feature high responsivity, fast signal response and a low temperature coefficient of operating voltage, all achieved at a low bias voltage.

The sensor is packaged in a compact and robust MLP (molded lead frame) package that is suitable for reflow solder processes. Both the sensor and the package are designed for volume production with the product delivered on tape and reel.

SiPM sensors are an improvement over avalanche photodiodes (APD) and PIN diodes due to their high gain and single photon sensitivity. This enables the detection of low reflectivity targets at very long distance in LiDAR applications. Unlike the similarly-operated SPAD that can only detect single photons, the SiPM overcomes this limitation by incorporating a ‘microcell’ structure that allows for multi-photon detection with a high dynamic range.

It is strongly recommended that those new to SiPM sensors consult the Introduction to Silicon Photomultipliers application note.
