Vishay Intertechnology High Speed PIN Photodiode Delivers Enhanced Sensitivity for Visible Light in Compact 2.0 mm x 1.8 mm x 0.6 mm SMD Package
February 01 2024 - 11:00AM
Vishay Intertechnology, Inc. (NYSE: VSH) today broadened its
optoelectronics portfolio with the introduction of a new high speed
silicon PIN photodiode with enhanced sensitivity for visible light.
Offered in a compact 2.0 mm by 1.8 mm by 0.6 mm top-view,
surface-mount package with clear epoxy for maximum sensitivity, the
Vishay Semiconductors VEMD2704 provides fast switching times of 70
ns and low capacitance of 17.6 pF for precise signal detection in
wearable devices.
With a radiant-sensitive area measuring 1.51 mm² — and high
radiant sensitivity with a reverse light current of 1.17 µA and
dark current of 0.03 nA — the device released today detects visible
and near infrared radiation over a wide spectrum range from 350 nm
to 1100 nm. In wearable devices such as fitness trackers and
smartwatches, the photodiode can be used with green LEDs for
optical heart rate detection and red LEDs for pulse oximetry
applications.
Offering a reduced size compared to previous-generation
solutions, the VEMD2074 enables easier integration into smaller
products like earbuds, allows several photodiodes to be included in
the optical system for more precise signal detection, and offers
increased flexibility in sensor placement. The device is also
available at a lower cost than previous-generation photodiodes,
making it ideal for cost-sensitive devices like smart bands.
The VEMD2704 features a ± 67° angle of half-sensitivity,
operating temperature range of -40 °C to +85 °C, and 940 nm
wavelength of peak sensitivity. RoHS-compliant, halogen-free, and
Vishay Green, the photodiode provides a moisture sensitivity level
(MSL) of 3 in accordance with J-STD-020 for a floor life of 168
hours.
Samples and production quantities of the VEMD2704 are available
now, with lead times of 20 weeks.
