Seoul Viosys UVC led chip 275nm CUD7QF1A
Product Details Description
The Seoul Viosys CUD7QF1A is a compact uvc led chip developed for deep ultraviolet light-source applications. It has a 275nm wavelength, 6.1V voltage, 20mA current, 2mW radiant power, and 120° view angle. The LED is designed for chemical and biological analysis applications where a small, SMT-solderable UVC component is required.
This uvc led chip has peak emission wavelengths from 270nm to 280nm. The 275nm output belongs to the UV-C / deep UV range and is different from UVA LEDs such as 365nm, 385nm, or 395nm. It is intended for specialized equipment designs rather than general visible inspection, blacklight display, or consumer flashlight use.
The CUD7QF1A is sealed in an EMC package with a silicone mold. Its 3.0 x 3.0mm size helps engineers build compact UVC light engines, analytical modules, prototype boards, and space-limited optical assemblies. The SMT solderable design supports modern board-level manufacturing and compact module integration.
For chemical and biological analysis, this uvc led chip can be used as a low-power deep UV source inside test equipment, sensing devices, laboratory modules, or optical analysis systems. Final system performance depends on optical path design, exposure distance, sample type, driver current, thermal structure, window material, and required UV dose.
The 120° view angle gives the CUD7QF1A a wide emission profile. This is useful when the module needs broad local coverage rather than a narrow focused spot. Engineers can also use a chamber structure, reflector, quartz window, or optical design to manage 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 selected when stronger thermal transfer is required. The product can be supplied as a component or assembled into customized UVC LED module boards.
Although the operating current is only 20mA, thermal and electrical design still matter. A suitable constant-current driver, correct soldering process, stable PCB structure, and safe insulation design should be used. Engineers should verify radiant output, board temperature, optical transmission, and application performance inside the final equipment.
This product is a component-level uvc led chip, not a complete finished lamp. A finished device should include a driver circuit, PCB board, housing, optical window, shielding, wiring, connector, warning label, and safety interlock when required. The CUD7QF1A should not be used in open-exposure products without proper UVC safety design.
UVC radiation can injure eyes and skin. Do not look directly at the operating LED, even briefly. Avoid direct skin exposure. Use protective eyewear, shielding, interlocks, warning labels, and safe working procedures during testing, assembly, and operation.
