MPPC® for automotive LiDAR
having high sensitivity in near infrared region at 905 nm


S15639-1325PS is a MPPC having high sensitivity in near infrared region for automotive LiDAR.

LiDAR is a remote sensing technology that measures distance by irradiating a laser light on objects and receiving the light reflected back with a photosensor.

Generally, the laser light having peak emission of near infrared (905 nm) is used for LiDAR. In case of measuring for a long distance accurately, high near infrared sensitivity and low afterpulse are required for the photosensors.

Newly released S15639-1325PS has realized high photon detection efficiency (9%) at near infrared region, and low afterpulse (1% max.).
