Seoul Viosys UVC led chip 275nm CUD7QF1A
Product Details Description
Seoul Viosys CUD7QF1A is a mini-size uvc led chip with deep ultraviolet emission applications. This component has a wavelength of 275nm, voltage of 6.1V, current of 20mA, radiant power of 2mW, and view angle of 120°. It is designed for chemical and biological analysis purposes and requires a mini-size, SMT-solderable UVC part.
Peak emission wavelengths for this uvc led chip are from 270nm to 280nm. 275nm light belongs to the UV-C / deep UV range and differs from UVA LEDs such as 365nm, 385nm, or 395nm. This product is designed for special equipment development and not for general visible light inspection, blacklight display, or consumer flashlight applications.
The CUD7QF1A is sealed in an EMC package with silicone mold. The 3.0 x 3.0mm size helps engineers to design a compact UVC light engine, analytical module, prototype board, or optical assembly. The SMT solderable technology allows for using modern board-level manufacturing and module integration.
For chemical and biological analysis purposes, this uvc led chip can be used as a low-power deep UV light source inside the test equipment, sensing devices, laboratory modules, or optical analysis systems. Final performance will depend on optical path design, exposure distance, sample type, driver current, thermal design, window material, and required UV dose.
The 120° view angle provides a wide emission area for the CUD7QF1A. It can be helpful when a module requires a wide local coverage but not a focused spot. Engineers can also implement a chamber structure, reflector, quartz window, or optical design to control the final UVC distribution.
For OEM and ODM projects, the CUD7QF1A can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB can be used for many compact module designs while copper PCB can be chosen if the thermal transfer is critical. This product can be delivered as a component or assembled into a customized UVC LED module board.
Though the operating current is only 20mA, thermal and electrical designs are still important. Suitable constant-current driver, correct soldering process, stable PCB structure, and safe insulation design should be implemented. Engineers should check radiant output, board temperature, optical transmission, and performance inside the final equipment.
This product is a component-level uvc led chip and not a finished lamp. Finished device should include a driver circuit, PCB board, housing, optical window, shielding, wiring, connector, warning label, and safety interlock if required. The CUD7QF1A shouldn’t be used in open-exposure products without proper UVC safety design.
UVC radiation can damage eyes and skin. Do not look at the operating LED even for a moment. Do not expose your skin to the deep UV light. Use protection glasses, shielding, interlocks, warning labels, and safe operating procedures during testing, assembling, and operation.
