New Launch: TH-UV255WFYT-TO39H-P3 255nm TO39 UVC LED – Ideal for Detection, Analysis and Sterilization

2026-05-30

Zhuhai Tianhui Electronic Co., Ltd. officially announces the launch of TH-UV255WFYT-TO39H-P3, a high-performance 255nm Uvc Led in a standard TO39 metal package. This product is specially optimized for detection and analytical applications, with verified optical and electrical performance supported by complete integrating sphere test reports.

The LED operates at 255nm peak wavelength (250–260nm range), with typical radiant flux of 1.5mW at 20mA forward current. It features narrow spectral half-width of 11nm and 7.5° viewing angle, providing concentrated and stable output for precision measurement and analytical scenarios.

Key specifications at Ta=25°C:

Forward voltage: 4.8–7.0V @ 20mA
Forward current: 20mA (typical), 60mA (max.)
Power dissipation: up to 380mW
ESD Class 1 (MIL-STD-883E)
Operating temperature: -15°C to +60°C
Storage temperature: -40°C to +85°C

This UVC LED is widely used in jewelry inspection, medical detection, biochemical analysis, air detection, water quality inspection and sterilization & disinfection equipment. Its compact TO39 outline, standardized dimensions and stable performance make it suitable for integration in professional instruments and industrial devices.

To support customer evaluation and design, we provide complete technical documents including:

Full integrating sphere test report (EVERFINE PCE-2000UV)
Official product datasheet (mechanical dimensions, electrical curves, application guidelines)

As an ESD-sensitive device, the product follows strict handling, storage and soldering requirements to ensure reliability and service life. Unopened packages can be stored for up to 3 months under <30°C and 70% RH, or up to 1 year in sealed desiccant containers.

We will continue to provide high-performance UVC LED solutions and professional technical support for analytical, environmental, medical and sterilization applications.
