UVC LED 6868: The LED68 Package Family

The family

The naming follows the same rule as the rest of the package programme: 68 denotes the 6868 format class, just as 35 denotes the 3535 class in the LED35 family. The dimensions name the nominal format class; the exact dimensions, tolerances and land pattern of a specific model are per-model documentation questions — ask what is recorded for the model you are sourcing. No comparison between the two LED68 models is recorded in this site's material, so which model carries which band and output class is established in the enquiry exchange.

Known facts, per-model questions, buyer inputs

• Known from the catalogue: the LED68 family name, its two catalogued models, and the nominal 6868 format class.
• To establish per model in the enquiry exchange: which of band and output class, exact dimensions and tolerances, land pattern, reflow conditions, optical characteristics and thermal ratings are documented for the named model, and what they show.
• What buyers provide: target band, the output the design needs per emitter position, board and thermal design, intended drive point and quantities.

Where the 6868 format is used

The LED68 family sits inside the package programme alongside the LED35 family, with configuration and output classes confirmed per model in the enquiry exchange. Published industry coverage of the company's earlier development work describes high-output demonstrations built as arrays of 6868-packaged devices; those reports describe development work of their time, not ratings for any model in the current catalogue.

Specifying an LED68 device

An enquiry for this family names the model — LED68c or LED68CGA — and the band the design is built around. State the output the design needs at each emitter position, the sustained drive point it will run at, and the board and thermal arrangement the position sits in. Ask which of the model's figures are recorded — band and output class, exact dimensions and tolerances, land pattern, reflow conditions, optical characteristics and thermal ratings — and have the answers confirmed in writing. Quantities, programme timing and any array layout the design assumes belong in the same first message.

Design notes

State the mounting, board material and heatsink arrangement your equipment provides when you enquire, and ask which drive conditions and thermal ratings are documented for the named model; output at the design's operating temperature is the figure the confirmation should answer against. Ask whether evaluation quantities can be supplied through the same enquiry route, against a named band and application.

Is the 6868 family a separate product line from the package programme?

No. The LED68 family is one of the two families inside the SMD package programme, alongside LED35.

The format in the published record

Industry coverage of the company's earlier development work, recorded as background in the company's own product record, describes a 1000 mW-class 275 nm UV-C lamp built as a 3×3 array of nine 6868-packaged devices, and a 100 mW 6868-packaged module used for flowing-water sterilization. Those are historical development reports from 2017, not ratings for any model in the current catalogue.
