Now in stock at New Yorker Electronics are two new surface-mount Automotive Grade silicon PIN photodiodes from Vishay Optoelectronics.

In a compact 0805 case size with a low 0.7 mm profile, these Vishay diodes are 0.15 mm lower than prior generation devices.

Offered in black packages, the opaque side walls of the Vishay Semiconductors VEMD4010X01 and VEMD4110X01 eliminate unwanted side illumination to increase their signal to noise ratio.

The photodiodes are used in photo detection applications such as solar load sensors; automotive rain, light, and tunnel sensors; light barriers for elevators, garage doors, and industrial equipment; and reflective sensors for touchless faucets, toilets, and trash cans.

For the detection of visible and near infrared radiation, the VEMD4010X01 offers a sensitivity range from 550nm to 1040nm.

For 740nm to 1040nm infrared applications, the VEMD4110X01 features a daylight blocking filter and is matched with 830nm to 950nm IR emitters.

They eliminate unwanted side illumination and increase signal-to-noise ratio.

The newly released Vishay Silicon PIN Photodiodes feature a sensitive area of 0.42 mm2. They provide a reverse light current of 2.4 µA and a low dark current of 1 nA.

The devices possess fast response times and ± 60° angles of half-sensitivity. The moisture sensitivity level (MSL) of 3 is in accordance with J-STD-020 for a floor life of 168 hours.
