GUVA-C22SD UV-A Sensor

The GUVA‑C22SD UV‑A Sensor is a Gallium Nitride Schottky‑type photodiode engineered for ultraviolet‑A detection in photovoltaic mode. It covers a spectral range of 240‑370 nm, with an active area of 0.076 mm² and a chip size of 0.4 mm housed in a COB 2418 package. The device delivers a responsivity of 0.14 A /W and can be stored from - 40 °C to +90 °C, while operating safely between - 30 °C and +85 °C. Additional electrical ratings include a reverse voltage of 5 V, a forward current of 1 mA, and a soldering temperature limit of 260 °C.

Gallium Nitride offers high electron mobility and low dark current, typical for UV sensors aimed at precise measurement. Industry‑standard GaN devices usually exhibit dark currents near 1 nA and a temperature coefficient of about 0.08 %/°C, both of which are listed for this sensor. The sensor also tolerates an optical source power range from 0.1 µW cm⁻² to 100 mW cm⁻², making it suitable for both low‑intensity ambient monitoring and high‑intensity lamp testing. Its compact COB form factor allows easy integration into handheld or embedded monitoring equipment.

Common uses involve UV‑A index monitoring stations, lamp certification rigs and portable UV exposure meters, where manufacturers need stable, low‑noise detection. OEMs in environmental instrumentation and lighting quality control typically source this component in batches for assembly. The listing does not provide minimum order quantities, unit pricing, or lead‑time details, so those figures should be confirmed with Week Technology Ltd. Trade conditions, Incoterms and payment structures are also to be negotiated with the supplier.

Week Technology Ltd. operates from the 16th floor of Building 3, Zhongke Mansion in Shenzhen, Guangdong, China. Classified as an imported supplier with a harbour trust tier, the firm participates in international component trade. Its response statistics show a 0 % response rate and no average response time recorded, indicating that inquiries may need follow‑up. Being situated in Shenzhen gives the company access to a dense network of electronic component manufacturers and logistics providers.

The product entry details the GUVA‑C22SD UV‑A Sensor and lists technical parameters such as spectral range, voltage ratings and temperature limits. No data are provided on certifications, warranty, or production capacity. Buyers should request these specifics directly from the supplier before finalising any purchase. The listing does not reference any third‑party audits or quality certifications.
