Two surface-mount Automotive Grade silicon PIN photodiodes in the compact 0805 case size with a low 0.7 mm profile — 0.15 mm lower than previous-generation devices – have been introduced by Vishay Intertechnology.

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 AEC-Q101 qualified photodiodes are optimised for photo detection in 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 wide sensitivity range from 550 nm to 1040 nm.

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

Delivering high sensitivity, the devices feature a sensitive area of 0.42 mm², reverse light current of 2.4 µA, and a low dark current of 1 nA.

The VEMD4010X01 and VEMD4110X01 offer fast response times, ± 60° angles of half-sensitivity, a wide temperature range of -40 °C to +110 °C, and 910 nm wavelengths of peak sensitivity.

RoHS-compliant, halogen-free, and Vishay Green, the photodiodes provide a moisture sensitivity level (MSL) of 3 in accordance with J-STD-020 for a floor life of 168 hours.
