Description
Introduction
The ams OSRAM DURIS® E 2835 (GW JTLPS2.EM) is an industry-standard mid-power LED designed for luminaire manufacturers who require a balance of high radiant power and proven industrial reliability. Built on a robust lead-frame platform, this 3V class component handles the thermal demands of high-density PCB arrays. The GW JTLPS2.EM is specifically binned for manufacturers of office troffers, linear industrial fixtures, and edge-lit panels who prioritize efficacy (lm/W) and long-term chromaticity stability.
For LED module manufacturers and fixture designers, the DURIS E 2835 offers a low-risk design path in the standardized 2835 footprint. Its optimized electrical characteristics allow engineers to simplify driver selection and circuit layout, effectively lowering the overall system Bill of Materials (BOM) without compromising on the quality of light.
Key Product Features
- Exceptional Luminous Efficacy: Optimized for high-output performance at a nominal 65mA drive current, allowing fixture manufacturers to meet strict Energy Star® or ErP efficacy standards with a lower component count.
- 1/9th Micro-Binning Support: Utilizing ams OSRAM's precision binning technology, this SKU ensures color coordinates fall within a very tight space. This effectively eliminates visible "checkerboard" color variation in large open-plan office installations.
- Industrial-Grade Lead-Frame Durability: Featuring a junction-to-solder point thermal resistance optimized for mid-power stability, the DURIS® E 2835 series protects the phosphor layer from premature yellowing in 24/7 commercial environments.
- Proven Reliability for B2B Supply: Backed by extensive LM-80 data, this component supports the long-term warranties required for municipal roadway and professional commercial project tenders.
- Consistent SMT Production Yield: Designed for automated pick-and-place lines, the component features consistent wetting properties during reflow, ensuring high assembly yields for contract manufacturers (EMS).

FAQ
Q: Is the GW JTLPS2.EM compatible with generic 2835 PCB layouts?
A: Yes. It follows the global industry standard for 2835 mid-power LEDs. It is a direct "drop-in" upgrade for fixtures currently using standard 3V 2835 components.
Q: Can I drive the GW JTLPS2.EM higher than the nominal 65mA current?
A: Yes, it is rated for up to 250mA. However, to maintain the L70 lifespan and ensure optimal efficacy, we recommend driving it between 65mA and 150mA, depending on your PCB's thermal management capacity.
Q: Does Gainer LED provide bin-matching for large linear installations?
A: Absolutely. We understand that for long-run LED strips, color consistency is paramount. We coordinate wholesale shipments to provide consistent flux and chromaticity bins across your entire order.
Q: How does this model handle sulfur-rich industrial environments?
A: ams OSRAM utilizes automotive-grade lead-frame materials for the DURIS® series, providing enhanced resistance to sulfurization and environmental stress compared to budget-tier SMD LEDs.
