Four-quadrant silicon PIN photodiode delivers excellent SNR

07-01-2021 | New Yorker Electronics | Lighting Technologies

New Yorker Electronics now offers Vishay’s industry first 4-Quadrant Silicon PIN Photodiode in a standard surface-mount package, qualified for automotive applications. Incorporating high photo sensitivity with low 0.1% electrical segment to segment crosstalk and practically no tolerance between its segments, the Vishay Semiconductors K857PE allows a mixture of sensor and control applications for the automotive, consumer and industrial markets.

This new device integrates four monolithic diodes combined into a single 4.72mm x 4.72mm x 0.8mm top-view, surface-mount package. The defined gap between the device's four radiant sensitive areas provides for dependable measurement during laser positioning. The opaque package sides stop stray light irradiating the photodiodes, producing an excellent signal to noise ratio while the linear photo response allows small signal detection.

The device retains an active area of 1.6mm2 per quadrant and offers a floor life rating of 168h, in accordance with J-STD-020. It provides a wide sensitivity range from 69nm to 1050nm, an 8.5µA reverse light current and a ±60-degree angle of half sensitivity. The device is AEC-Q101 qualified, RoHS-compliant, halogen-free and Vishay Green.

Typical applications include small signal detection for automotive rain/light sensors, industrial automation systems, laser beam alignment, and virtual reality.
