The News:

To meet the need for reliable signal detection in wearable devices and medical and industrial applications, Vishay

Intertechnology broadens its optoelectronics portfolio with the introduction of two new high speed silicon PIN

photodiodes that deliver enhanced sensitivity for visible light. Featuring infrared radiation suppression filters and

black packages for an improved signal-to-noise ratio, the Vishay Semiconductors VEMD5510C and VEMD5510CF

offer fast switching times and low capacitance in compact top-view, surface-mount packages.

On-chip suppression filters eliminate disturbances from non-visible light
Black packages block unwanted lateral Illumination
Spectral sensitivity of < 5 % for wavelengths > 800 nm for the VEMD5510C and > 700 nm for the VEMD5510CF— closely matching that of the human eye
Small size and sensitivity enable slim sensor designs for optical rate measurement in wearable devices such as fitness trackers and smart watches
