Electronics Semiconductors opto photodiode semiconductorVISHAY SEMICONDUCTORS K857PE 4-Quadrant Silicon PIN Photodiode boosts signal-to-noise ratio with virtually no tolerance between segments. Available in a standard surface-mount package, device is qualified for automotive applications. Combining high photo sensitivity with low 0.1% electrical segment to segment crosstalk and virtually no tolerance between its segments, device enables a variety of sensor and control applications for the automotive, consumer and industrial markets. Device combines four monolithic diodes integrated into a single 4.72mm x 4.72mm x 0.8mm top-view, surface-mount package. The defined gap between the product’s four radiant sensitive areas allows for reliable measurement during laser positioning. The opaque package sides eliminate stray light irradiating the photodiodes, resulting in excellent signal to noise ratio while the linear photo response enables small signal detection. The current from each of the device’s PIN diodes can be processed individually. This results in low 0.1 % electrical crosstalk and virtually no tolerance between segments.
