Enhanced Sensitivity in Biomedical Applications with Silicon PIN Photodiode

The VEMD8082 PIN photodiode has set a new standard in light sensing technology with its advanced features and compact design. Compared to its predecessors, this cutting-edge device offers increased reverse light current, reduced diode capacitance, and faster rise and fall times. Its small form factor of 4.8 by 2.5 by 0.5 mm makes it ideal for integration into low-profile devices like smart watches, opening up a world of possibilities for innovative applications.

One of the key advantages of the VEMD8082 is its high sensitivity, which is particularly valuable in biomedical applications such as photoplethysmography (PPG). In PPG, the photodiode plays a crucial role in detecting changes in blood volume and flow by measuring the light absorbed or reflected by blood vessels. Accurate and precise measurements are essential for diagnosing and monitoring conditions like cardiovascular disease, making the VEMD8082 a game-changer in the field of healthcare technology.

The specifications of the VEMD8082 contribute significantly to its enhanced sensitivity. With a radiant sensitive area of 6.0 mm² and an increase in reverse light current ranging from 18% to 20% depending on the wavelength, this photodiode delivers exceptional performance. Furthermore, the reduction in diode capacitance from 50 pF to 46 pF and faster rise times of 40 ns compared to 110 ns enable higher sampling rates, allowing for more precise data capture and analysis.

Both samples and production quantities of the VEMD8082 PIN photodiode are readily available, offering engineers and developers the opportunity to experience the benefits of this groundbreaking technology firsthand. Whether you are working on a new wearable device, a medical instrument, or any other light sensing application, the VEMD8082 promises to elevate the performance and efficiency of your product.
