ON Semiconductor Launches World's First Automotive Qualified SiPM Array Product for LiDAR Applications

The ArrayRDM-0112A20-QFN is AEC-Q102 qualified and developed in accordance with IATF 16949.

ON Semiconductor announced the new RDM-Series silicon photomultiplier (SiPM) array that extends the LiDAR sensor capabilities to its portfolio of intelligent sensing solutions. Per the company, the ArrayRDM-0112A20-QFN is the first automotive qualified SiPM product in the market, ready for the demands in LiDAR applications for the automotive industry and beyond.
The ArrayRDM-0112A20-QFN is a monolithic 1×12 array of SiPM pixels based on the company's RDM process, which enables high sensitivity to near-infrared (NIR) light to achieve 18.5% photon detection efficiency (PDE)(1) at 905 nanometers (nm). The high internal gain of the SiPM allows sensitivity down to the single-photon level, a feature that in combination with the high PDE, enables the detection of the faintest return signals. This results in the ability to range to greater distances even with low reflective targets.

SiPMs have the ability to deliver the suitable signal-to-noise performance for long distance ranging in bright sunlight conditions. Additional benefits including low supply biases and low sensitivity to temperature changes make it an ideal upgrade for systems that use legacy avalanche photodiodes (APDs). Per the company, SiPMs are produced in a high-volume CMOS process, allowing for a low detector cost.
