Vishay High Speed PIN Photodiode Delivers Precise Signal Detection, Enables Slim Sensor Designs for Wearables

Vishay Intertechnology optoelectronics portfolio

Vishay Intertechnology ‘s new Device Offers Enhanced Sensitivity for Visible Light in 5 mm by 4 mm SMD Package With Low 0.9 mm Profile

Vishay Intertechnology broadens its optoelectronics portfolio unveils new high speed silicon PIN photodiode with enhanced sensitivity for visible light.

Offered in a compact 5 mm by 4 mm top-view, surface-mount package with a low 0.9 mm profile, the Vishay Semiconductors VEMD5080X01 offers fast switching times and low capacitance for precise signal detection in wearable devices and medical, industrial, and automotive applications.

Offering a large radiant-sensitive area measuring 7.5 mm² — and high radiant sensitivity with a reverse light current of 45 µA and dark current of 0.2 nA — the device released today detects visible and near infrared radiation over a wide sensitivity range from 350 nm to 1100 nm.

For green LEDs, the VEMD5080X01’s sensitivity represents a 30% improvement over previous-generation solutions.

When used with Vishay’s VLMTG1400 green LED, the photodiode’s small size and sensitivity enable slim sensor designs for optical heart rate detection in wearable devices such as fitness trackers and smart watches.

When combined with Vishay’s VSMD66694 660 nm and 940 nm dual color emitting diodes, the device is ideal for SpO2 measurement in medical monitors.

In addition, it provides high speed photo detection in smoke detectors with dual-wavelength light sources and automotive dust and particle sensors in combination with a red diode.

The VEMD5080X01 features a ± 65° angle of half-sensitivity, a wide temperature range of -40 °C to +110 °C, and 950 nm wavelength of peak sensitivity. The robust device is tested to AEC-Q101 standards for Automotive Grade semiconductors. RoHS-compliant, halogen-free, and Vishay Green, the photodiode provides a moisture sensitivity level (MSL) of 4 in accordance with J-STD-020 for a floor life of 72 hours. Wettable flanks allow for optical solder joint inspection.


Samples and production quantities of the VEMD5080X01 are available now, with lead times of eight to 10 weeks for large orders.
