K857PE is first four-quadrant silicon PIN SM photodiode, says Vishay Intertechnology
Believed to be the first four-quadrant silicon PIN photodiode in a standard surface mount (SM) package and qualified for automotive applications, the K857PE has been released by Vishay Intertechnology.
It combines high photo sensitivity with 0.1 per cent crosstalk and virtually no tolerance between its segments, says Vishay Semiconductors. The K857PE enables a variety of sensor and control applications for the automotive, consumer, and industrial markets.
The AEC-Q101-qualified device released today has four monolithic PIN diodes – each with an active area of 1.6mm² and which are integrated into a single 4.72 x 4.72 x 0.8mm top-view, surface mount package. The sides of the K857PE’s package are opaque, which eliminates stray light irradiating the photodiodes, resulting in excellent signal to noise ratio, says Vishay. The linear photo response enables small signal detection for automotive rain / light sensors, industrial automation systems, laser beam alignment, and virtual reality applications.
The photodiodes are built on epitaxial technology and offers a wide sensitivity range from 690 to 1050nm, with 8.5 microA reverse light current per segment at Ee = 1 mW per cm² and an 850nm wavelength. The K857PE features a daylight blocking filter, ± 60 degrees angle of half sensitivity, and operates over a temperature range of -40 to +110 degrees C. The K857PE offers a floor life of 168h in accordance with J-STD-020 and is RoHS-compliant and halogen-free.
The four-quadrant photodiodes are available now, with lead times of 10 weeks for production quantities.
Vishay manufactures one of the world’s largest portfolios of discrete semiconductors and passive electronic components for designs in the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
