The GUVA-T11GD-L is a Gallium-Nitride based Schottky-type photodiode designed for UV-A lamp monitoring. It operates in photovoltaic mode with a dark current of 20 nA and a photo current ranging from 2.8 to 3.4 µA (typical 3.1 µA) at 25°C. The sensor offers a responsivity of 0.18 A/W and a spectral detection range of 220 nm to 370 nm. Its absolute maximum ratings include storage temperature -40°C to 90°C, operating temperature -30°C to 85°C, reverse voltage 5 V and forward current 1 mA.
Gallium-nitride provides high solar blindness, meaning visible light does not interfere with UV detection, a common requirement in industrial lamp control. The active area of 1.536 mm² and a temperature coefficient of 0.05 %/C are typical for precision UV sensors used in harsh environments. Standard industry practice packages such devices in surface-mount SMD housings, allowing automated assembly; this is a typical packaging format. The sensor tolerates a soldering temperature up to 260°C, aligning with standard lead-free reflow profiles.
Primary users include manufacturers of UV-A curing equipment, laboratory instrument makers and facilities that monitor lamp performance for safety compliance. Week Technology Ltd. lists the product under imported tier with a harbor trust level, and buyers can request FOB or CIF terms based on their logistics needs. Prospective importers should confirm MOQ, lead time and any required certifications directly with the supplier.

Before placing an order for the GUVA‑T11GD‑L sensor, importers should verify the exact device package, confirm that the sensor meets any required regulatory standards such as RoHS or CE, and request a datasheet that includes the calibration curve. It is also prudent to ask for sample units to validate dark current and responsivity against the stated 20 nA and 0.18 A/W values. Any deviation should be clarified with the supplier.
Week Technology Ltd. ships from Shenzhen, so buyers need to confirm the preferred Incoterm, typically FOB Shenzhen Port or CIF Shanghai, and align container or air freight schedules with their production timeline. The listing does not disclose lead time, so importers should request an estimated production and dispatch period. Payment methods such as T/T against LC or PayPal for small samples are common, but the exact terms must be negotiated directly.
When the shipment arrives, conduct a visual inspection for physical damage and verify the part numbers against the purchase order. Functional testing should include measuring dark current at 25°C and checking responsivity with a calibrated UV‑A source to ensure it meets the 0.18 A/W specification. Request a test report or certificate of calibration, and retain the inspection records for customs and quality assurance purposes.
