S3759Si PIN photodiode


Datasheet [127 KB/PDF]

Si PIN photodiode for visible to infrared photometry


The S3759 is a Si PIN photodiode developed to detect and measure infrared energy emitted from YAG lasers (1.06 um). Compared to standard Si photodiodes, the S3759 delivers exceptionally high sensitivity of 0.38 A/W at 1.06 um. The PIN structure allows high-speed response and low capacitance. The photosensitive area is as large as φ5 mm, making optical axis alignment easier.
