Vishay Intertechnology has developed two new 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. 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 released are optimized 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
