Silicon PIN Photodetector – 2.5mm, 400–1100nm Broadband for Optical Sensing

More surface area. More signal. More accuracy.

With a larger 2.5mm × 2.5mm active area, this silicon PIN photodetector captures more light than smaller sensors — making it the right choice when you need stronger signal output or are working with diverging beams and wider light sources.

• 400–1100nm broadband response — visible to near-infrared coverage
• 2.5mm × 2.5mm active area — larger capture area for stronger signal
• High responsivity: 0.5mA/mW @ 850nm, 0.35mA/mW @ 650nm
• Ultra-low dark current: 0.2nA @ -5V for clean, low-noise detection
• TO-5 package — standard, easy to integrate into existing designs

Ideal for optical power meters, industrial light sensors, space light detection, and scientific analysis systems.
