Vishay Intertechnology introduced the VEMD8083, a compact 3.2 mm × 2.0 mm × 0.6 mm silicon PIN photodiode that delivers a 2.8 mm² sensitive area and 30 ns rise/fall times. The device’s reverse light currents—11 µA at 525 nm, 14 µA at 660 nm, and 16 µA at 940 nm—enable fast, low‑noise performance across visible and near‑infrared wavelengths, while its 50 pF capacitance and –40 °C to +85 °C operating range make it suitable for rugged biomedical and consumer health applications.
The VEMD8083’s specifications are tailored for the growing wearables market. Its small footprint and high‑speed response allow it to be integrated into smart‑ring and wrist‑band designs that monitor heart rate, blood‑oxygen saturation, and photoplethysmography signals. The 30 ns rise/fall time translates to a bandwidth that can capture rapid physiological changes, improving measurement accuracy in consumer health devices.
Vishay’s optoelectronics portfolio has expanded steadily, with the 2024 launch of the VEMD2704 and a suite of high‑power IR emitters in May 2024. The VEMD8083 builds on that momentum by offering a more sensitive, faster photodiode that targets the same high‑growth segments. Analysts estimate the global wearable sensor market will reach $30 billion by 2030, and Vishay’s new product positions it to capture a share of that upside by providing a differentiated component for heart‑rate and blood‑oxygen monitoring.
The launch aligns with Vishay’s broader strategy to focus on high‑growth, high‑margin markets such as automotive, aerospace, and health‑tech. In its Q3 2025 earnings, Vishay reported a 7.5 % revenue increase to $790.6 million, driven largely by its MOSFETs and capacitors segments, while optoelectronics revenue fell 12 % YoY. By adding the VEMD8083, Vishay aims to offset the optoelectronics decline with a product that can drive new revenue streams in wearables and medical devices.
"Our third‑quarter results demonstrate that we are successfully capitalizing on high‑growth markets, including smart‑grid infrastructure, AI‑related power needs, automotive, and aerospace/defense," said Joel Smejkal, President and CEO. "The VEMD8083 is a key part of our strategy to expand into the rapidly growing wearables and health‑tech sectors, where our high‑performance photodiodes can deliver the speed and sensitivity required for next‑generation monitoring devices."
