Overview of QSB34GR by onsemi
The QSB34GR is a surface mount silicon infrared PIN photodiode, notable for its PLCC-2 package and a peak sensitivity wavelength of 940 nm. This component is equipped with two pins and conforms to a diode case style called PLCC. It exhibits a relatively modest dark current of 0.03 µA and offers an angle of half sensitivity at ±60°, making it suitable for various light detection scenarios. Specified to operate over a temperature range from -25°C to 85°C, its robustness is complemented by its compliance with RoHS standards, ensuring its utility in environmentally sensitive applications.
Created by onsemi, the QSB34GR emphasizes reliability with operational parameters like a dark current maximum of 30 nA and an efficient light current nominal of 0.037 mA. The device is tailor-made for applications requiring precise infrared wavelength detection, thanks to its infrared range specification and daylight filter feature. With a reverse breakdown voltage minimum of 32 V and a matching reverse voltage maximum, it assures durability under varied electrical conditions. This photodiode’s design incorporates a rectangular shape in a compact size of 4.4 mm, geared to facilitate ease of mounting in surface mount technologies (SMT).
Industry Applications for QSB34GR
The QSB34GR photodiode’s properties allow it to serve potentially in various industry applications though it is essential that each use case be evaluated by engineering and design teams to ensure compliance with industry-specific standards and requirements. Here are a few possible industry applications:
- Energy and Power Systems: The ability to operate across a wide temperature range and sensitivity to infrared light might make the QSB34GR suitable for monitoring and controlling radiant heating systems, where accurate heat sensing is crucial.
- Renewable Energy: In solar energy setups, particularly solar thermal power plants, the detection and measurement of infrared light could potentially be used to enhance the efficiency of heat exchangers.
- Automotive: Given its precise wavelength detection and daylight filtering feature, the QSB34GR might be used in automotive applications such as driver assistance systems where infrared light sensing plays a critical role in night vision enhancements. Note, however, that specific compliance with automotive industry standards like AEC-Q100 or Q101 would need to be verified.
Please note: these potential industry applications are conceptual and require thorough verification for practical implementation.
