Vishay BPW21R Silicon Photodiode
The BPW21R is a planar silicon PIN photodiode designed for high-precision linear applications. It features high dark resistance, ensuring linear short-circuit photocurrent over seven decades of illumination, and a logarithmic relationship between open-circuit voltage and illumination. Equipped with a flat glass window with a built-in color correction filter matching human eye response, it offers high photosensitivity, low dark current, high shunt resistance, and excellent linearity. Suitable for sensors in exposure, color measurement, and instrumentation, the diode has a body diameter of 8.13mm, a ±50° angle of half sensitivity, and is hermetically sealed for reliability.
