Overview

The VSMY2850RG is a high-speed infrared emitting diode based on Surface-to-Emitter technology, featuring a peak wavelength of 850nm. It is housed in a compact reverse gullwing SMD package and offers a narrow 20-degree viewing angle for high radiant intensity. This emitter is designed for high pulse current operation, delivering up to 70mW/sr at 100mA forward current.

Why Choose This Part

The component utilizes Vishay's SurfLight technology, which ensures that most of the generated light is emitted directly through the top surface for high efficiency. Its low forward voltage of 1.6V and capability for high pulse current up to 1A allow for intense illumination in short bursts. The 20-degree viewing angle eliminates the need for external optics in many short-to-medium range applications.

Applications

Infrared Data Transmission
High-speed switching capabilities make it suitable for short-range wireless IR communication links.
Photoelectric Sensors
The narrow beam angle and high radiant power allow for precise object detection in reflective and transmissive optical sensors.
Proximity and Gesture Sensing
Provides the IR illumination necessary for gesture control systems and proximity detection in industrial environments.
Light Curtains
Used in safety light curtains where focused IR beams are required to detect intrusion.

Getting Started

When integrating this IR LED, ensure the forward current is limited by a series resistor or constant-current driver tailored to the 1.6V forward voltage. For high-pulse operation, verify the duty cycle complies with the datasheet to prevent thermal damage. The reverse gullwing package is optimized for PCB mounting where the emitter faces through a cutout or toward the board surface.
