RD-SERIES SIPM中文资料Silicon Photomultipliers, NIR-Enhanced, Automotive Qualified数据手册ONSEMI规格书

描述 Description

The RD-Series is the latest range of 1mm Silicon Photomultipliers (SiPM) that provide increased sensitivity into the red and NIR region of the electromagnetic spectrum. The RD sensors feature single photon sensitivity, high responsivity and fast signal response, all achieved at a low bias voltage. The sensor is packaged in a compact and robust micro leadframe package (MLP) that is suitable for reflow solder processes. In order to meet the requirements for automotive LiDAR applications, this product will be qualified to AEC−Q102 and has been developed in accordance with IATF 16949.

The primary application for the RD-Series SiPM sensors is for LiDAR and ranging applications that use NIR wavelengths. SiPM sensors are an improvement over avalanche photodiodes (APD) and PIN diodes due to their high gain and single photon sensitivity. For LiDAR applications, this enables the detection of low reflectivity targets at very long distance. 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 recommended that those new to SiPM sensors consult the Introduction to Silicon Photomultipliers application note.
