SFH 47167B
Overview
The SFH 47167B is a high-power infrared (IR) OSLON Black emitter with a centroid wavelength of 850nm, designed for high-efficiency illumination tasks. It features a low thermal resistance of 3.6 K/W and is capable of handling a forward current up to 1A, making it suitable for compact, high-output sensing applications.
Why Choose This Part
This emitter offers exceptional thermal management with a max thermal resistance of 3.6 K/W, allowing for sustained 1A operation in small 1515 packages. Its 68-degree viewing angle provides a concentrated beam for improved range, while the 2kV ESD rating ensures robustness in assembly and field use.
Applications
Key Specifications
Getting Started
When designing with the SFH 47167B, ensure the PCB layout includes adequate thermal vias to manage heat dissipation at the 1A maximum current. Drivers should provide constant current regulation to maintain a typical forward voltage of 1.6V and prevent thermal runaway.
