New Yorker Electronics broadens Optoelectronics Line with Vishay High-Speed PIN Photodiode

Vishay Optoelectronics Automotive Grade PIN Photodiodes with Increased Signal-to-Noise Ratio

New Vishay VEMD8081 High Speed PIN Photodiode Enables Improved Bio Sensor Performance, Slim Design for Wearables

February 9, 2021- New Yorker Electronics has added the new Vishay Semiconductors VEMD8081 High-Speed and Highs-Sensitivity PIN photodiode with enhanced sensitivity for visible light. The Vishay PIN Photodiode provides increased photocurrent of 33µA in a 4.8mm by 2.5mm SMD package with a 5.4 mm2 sensitive area detecting visible and near infrared radiation.

Part Number Information
VEMD8081

Designed at a slim 0.48mm height, the device is idea for optical heart rate detection in wearable devices such as fitness trackers and smartwatches when placed between two pulsing green LEDs. They are also used in SpO2 measurement in medical monitors when combined with red and infrared emitters.

The new Vishay VEMD8081 offers 15-percent greater reverse light current than its predecessor, the Vishay VEMD8080, while maintaining the same package dimensions. It utilizes Vishay’s proven wafer technology to detect visible and near infrared radiation. The device provides designers with a drop-in replacement that can improve performance by increasing signal output, or extend battery life by reducing LED current.

The VEMD8081’s rectangular shape maximizes the area of the photodiode receiving reflected light, eliminating the wasted area typically found in square photodiodes. For heart rate measurement in wearable devices, the light reflected off the skin is received by the photodiode and converted to an output current, with the device’s increased sensitivity enabling more accurate measurements.

Samples and production quantities of the VEMD8081 are available now, with lead times of 10 weeks. New Yorker Electronics supplies Vishay Optoelectronics Optocouplers, Optical Sensors, 7-Segment Displays, Infrared Receivers, Solid-State Relays, LCD Displays, Visible LEDs, Infrared Emitters, Plasma Displays, Photo Detectors, IrDA Transceivers and Infrared Touch Panels.
