Vishay Intertechnology has introduced a new Automotive Grade 4-quadrant silicon PIN photodiode K857PH that combines high photosensitivity with low 0.1 % crosstalk and virtually no tolerance between its segments. The device’s linear photoresponse enables small signal detection for automotive rain / light sensors, industrial automation systems, laser beam alignment, and virtual reality applications. This AEC-Q101 qualified device features four monolithic PIN diodes each with an active area of 1.6 mm² integrated into a single 4.72 mm by 4.72 mm by 0.8 mm top-view surface-mount package.

 

Built on homogenous technology, this photodiode offers a wide sensitivity range from 710 nm to 1100 nm, a peak wavelength of sensitivity of 950 nm, and a reverse light current of 11 µA per segment at Ee = 1 mW/cm². It provides a ± 60° angle of half sensitivity and operates over a temperature range of -40 °C to +110 °C. Moreover, the sides of this device’s package are opaque which eliminates stray light irradiating the photodiodes, resulting in an excellent signal-to-noise ratio.
