The Optoelectronics Group of Vishay Intertechnology Inc. has launced the industry’s first four-quadrant silicon PIN photodiode in a standard surface-mount package, qualified for automotive applications. Combining high photo sensitivity with low 0.1% crosstalk and virtually no tolerance between its segments, the Vishay Semiconductors K857PE enables a variety of sensor and control applications for the automotive, consumer and industrial markets.
The 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. The sides of the K857PE package are opaque, which eliminates stray light irradiating the photodiodes, resulting in excellent

Built on epitaxial technology, the photodiode offers a wide sensitivity range from 690 nm to 1050 nm, with 8.5 µA reverse light current per segment at irradiance (Ee) = 1 mW/cm2 and an 850 nm wavelength. The device features a daylight blocking filter, ± 60° angle of half sensitivity and operates over a temperature range of -40˚ C to 110˚ C. RoHS-compliant, halogen-free,and Vishay Green, the K857PE offers a floor life of 168 hours in accordance with J-STD-020.
Samples of the new four-quadrant photodiode are available now with lead times of 10 weeks for production quantities. Pricing for U.S. delivery starts at $1.10 per piece in 1,000-piece quantities.
