The QSD2030F is a plastic silicon PIN photodiode designed for light detection applications. It features a peak sensitivity wavelength of 880 nm, a wide reception angle of 40 degrees, and is housed in a black epoxy T-1 3/4 package that acts as a daylight filter. Key characteristics include a fast rise and fall time of 5 ns, a low reverse dark current of 10 nA, and a typical reverse light current of 25 µA. The device is rated for a wide operating temperature range of -40°C to +100°C. Its high sensitivity and fast switching speed make it suitable for a variety of general-purpose photo-detection circuits.
