Vishay Intertechnology has introduced a new Automotive Grade 4-quadrant silicon PIN photodiode K857PH that combines high photo sensitivity with low 0.1 % crosstalk and virtually no tolerance between its segments. The device’s linear photo response 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 and sides of this device’s package are opaque which eliminates stray light irradiating the photodiodes, resulting in excellent signal to noise ratio.
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 reverse light current of 11 µA per segment at Ee = 1 mW/cm². Moreover, it provides a ± 60° angle of half sensitivity and operates over a temperature range of -40 °C to +110 °C.
Samples and production quantities of the new 4-quadrant K857PH photodiode are now available with lead times of 10 weeks.
