K857PE Four-Quadrant Silicon PIN Photodiode

Vishay's four-quadrant silicon PIN photodiode is offered in a standard surface-mount package and is qualified for automotive applications. Combining high photosensitivity with low (0.1%) electrical segment-to-segment crosstalk and virtually no tolerance between its segments, the K857PE enables a variety of sensor and control applications for the automotive, consumer, and industrial markets. Opaque package sides eliminate stray light irradiating the photodiodes resulting in an excellent signal-to-noise ratio. Linear photo response enables small signal detection. The defined gap between the K857PE’s four radiant sensitive areas allows for reliable measurement during laser positioning. The current from each of the device's PIN diodes can be processed individually, resulting in low electrical crosstalk.
