Wavelength-sensitive photodiode C30642GH-LC

LIDARInGaAsinfrared

Description
The C30642GH-LC is a large-area InGaAs PIN photodiode featuring a 2.0 mm active diameter chip housed in a TO-5 package with a flat glass window. It delivers high quantum efficiency across 800–1700 nm, ultra-low capacitance (approximately 50% of standard types) for roughly twice the 3 dB bandwidth, high responsivity, high shunt resistance and very low dark current. Typical devices show less than 1% non-linearity and uniformity within 2% over the active area, making the detector suitable for precision optical measurement and high-speed applications.
