ams OSRAM SFH 4554 850nm High-Power Infrared LED 5mm Radial Narrow Beam IR Emitter

Introduction

The ams OSRAM SFH 4554 is a professional-grade, high-power infrared emitter engineered for manufacturers who require intense radiant power and a tightly controlled beam pattern. Built on a standardized 5mm radial (T 1 3/4) footprint, this component delivers a peak wavelength of 850 nm, providing the optimal spectral response for high-sensitivity security cameras and optical sensors. The SFH 4554 is specifically designed to achieve a narrow 20-degree beam, facilitating superior "light-on-target" over long distances without the immediate need for secondary focusing lenses.

For LED module manufacturers and industrial sensor designers, the SFH 4554 serves as a cost-effective "workhorse." Its ability to handle high drive currents while maintaining high radiant intensity makes it a strategic choice for large-scale production of light barriers, smoke detectors, and infrared data transmission modules.

Key Product Features

• Precision 20° Narrow Beam: The integrated lens concentrates the infrared energy into a tight ± 10° half-angle. This allows fixture manufacturers to maximize the effective range of their sensing devices while minimizing light spill.
• High Radiant Intensity (Ie): Delivering up to 550 mW/sr at a nominal 100mA current, the SFH 4554 ensures that distant objects are clearly illuminated for CMOS/CCD receptors.
• Optimized 850nm Efficiency: 850nm is the industry standard for high-performance sensing. It offers significantly higher quantum efficiency (QE) with standard silicon detectors compared to 940nm emitters, enabling lower power consumption for the same detection distance.
• Ultrafast Switching Speed: With typical rise and fall times of only 12 ns, this emitter is perfectly suited for high-speed pulse modulation, supporting data rates required for optical communication and high-frequency barriers.
• Industrial-Grade Thru-Hole Design: The rugged lead-frame construction ensures stable mechanical mounting and reliable wave soldering performance, supporting the long-term field stability required for municipal and security projects.

The SFH 4554 series is a staple light source for performance-driven markets:

• Infrared Illumination for Cameras: High-throw 850nm sources for night vision in high-clearance warehouses and perimeter security.
• Industrial Light Barriers: Precise, fast-switching emitters for object counting, limit switches, and safety light curtains.
• Smoke and Particle Detectors: Reliable, long-life monochromatic emitters for sensitive scattering-based detection systems.
• Distance and Rangefinding: Consistent pulse-modulated emitters for handheld and fixed-position distance measurement tools.
• Remote Control & Data Links: High-speed emitters for professional industrial remote control systems.
