Si PIN photodiode


Photodiode with mini-lens, high-speed response (1 GHz)

The S5973-01 is a high-speed Si PIN photodiode designed for visible to near infrared light detection. The mini-lens type photodiode can be efficiently coupled to an optical fiber. This photodiode provides wideband characteristics at a low bias, making them suitable for optical communications and other high-speed photometry.

-High-speed response: 1 GHz (VR=3.3 V)
-Low price
-High reliability
