ams OSRAM GW PUSRA1.EM DURIS® P 10 High-Efficacy 3737 White LED

Introduction

The ams OSRAM DURIS® P 10 (GW PUSRA1.EM) represents a strategic performance benchmark for manufacturers of high-power industrial lighting. Engineered to deliver exceptional radiant intensity within a standardized 3.75 mm x 3.75 mm footprint, the P 10 series is designed to handle the thermal demands of high-density PCB arrays. The GW PUSRA1.EM is the primary choice for LED module manufacturers and fixture designers who prioritize lumens-per-watt (lm/W) efficacy and predictable aging characteristics.

Built on an advanced epoxy-based high-power package, this component facilitates efficient heat transfer and superior sulfur resistance. By utilizing Lumileds' proprietary binning at 85°C, it ensures that the daylight white performance matches real-world fixture operating temperatures, reducing the design margin of error for professional roadway and high-bay tenders.

Key Product Features

• Optimized High-Lumen Density: Characterized at a nominal 700mA, the GW PUSRA1.EM allows fixture manufacturers to achieve target brightness packages with a lower component count, effectively reducing the overall Bill of Materials (BOM) cost.
• Superior Thermal Path Reliability: Featuring a junction-to-solder point thermal resistance of typically 2.4 K/W, this series ensures rapid heat dissipation. This thermal stability protects the InGaN chip during continuous high-current operation, preserving the L70/L90 lifespan.
• Hot-Color Targeting at 85 °C: Unlike budget-grade LEDs rated only at 25 °C, ams OSRAM bins this part at actual fixture operating temperatures. This ensures minimal "tint-shift" once the finished lamp reaches thermal equilibrium on-site.
• Industrial-Grade Durability: Built with high-reliability silicone and robust lead-frame materials, the P 10 series offers exceptional resistance to sulfurization (Corrosion Class 3B), a mandatory requirement for high-pollution industrial zones or municipal roadway contracts.
• SMT Production Reliability: Designed for automated pick-and-place lines, the GW PUSRA1.EM features consistent wetting properties during reflow, reducing manufacturing defects for contract manufacturers (EMS).

The GW PUSRA1.EM series is a staple light source for performance-driven arrays:

• Industrial High-Bay & Low-Bay: Consistent, high-intensity daylight white sources for warehouses requiring high alertness and visibility.
• Municipal Street Lighting: High-throw efficacy for roadway infrastructure projects targeting Energy Star® or DLC® Premium certifications.
• Parking Lot & Area Floodlighting: Durable light engines for high-throw perimeter lighting requiring 50,000+ hour maintenance cycles.
• Specialty Spotlights: Compact high-power emitters for industrial-grade PAR lamps and high-output directional fixtures.
