2-Pin SMD 660nm Red Light + 905nm Near-Infrared Emitting LED
A compact dual-wavelength SMD LED integrating 660nm red light and 905nm near-infrared chips in one package, designed for medical sensing, beauty therapy, skin testing, biometric recognition, and optical detection applications.
Product Overview
This 2-pin SMD dual-wavelength emitting LED is independently packaged by Jiangmen Yiyang Infrared Semiconductor. It integrates a 660nm red light chip and a 905nm near-infrared chip into a single compact surface-mount package. The high-transparency white epoxy housing provides uniform light transmission and good heat resistance, while the gold-plated pads offer excellent conductivity and soldering stability. The device is compatible with fully automatic SMT mounting lines and can pass standard reflow soldering. A single component can output both visible red light and infrared light, simplifying PCB layout and reducing assembly complexity.

Dual-Wavelength Integrated Design
One LED outputs both red light and infrared light, reducing the need to mount two separate LEDs, saving PCB space, simplifying circuit design, and lowering material and SMT assembly costs.
Gold-Plated Pads for Stable Soldering
Thick gold-plated pads resist oxidation and provide excellent solder paste wetting, reducing weak soldering and pad detachment during reflow soldering.
High Dual-Chip Consistency
Chips are mounted and wire-bonded in a dust-free factory environment, ensuring small differences in red and infrared output intensity within the same batch for stable detection data.
Reflow Soldering Compatible
The high-temperature epoxy package can withstand short-time reflow soldering with peak temperature up to 260℃, supporting fully automated production without manual post-soldering.
Full Specification Customization
Red and infrared power ratio, emitting angle, package size, and special wavelength options can be customized. Small-batch samples and matched infrared receiver components are available.
Factory Inspection for Quality Control
Each product is checked for wavelength sorting, voltage, and solder pad quality before shipment, helping ensure consistent performance and stable long-term supply.
Main Application Scenarios
- Medical & Health Detection Devices Pulse oximeters, pulse detection instruments, skin testers, vein imaging devices, and non-invasive glucose detection modules.
- Beauty & Therapy Instruments Red light beauty masks, infrared therapy devices, photorejuvenation instruments, and scalp care devices.
- Biometric Sensing Fingerprint vein recognition, liveness detection, and optical ranging sensors.
- Industrial Optical Detection Material composition detection, optical scanning, and transmission-type infrared detection modules.
- Home Portable Instruments Portable health testing devices, compact therapy instruments, and household optical care equipment.
SMT Soldering & Usage Notes
- Reflow Temperature Recommended peak reflow temperature should be ≤260℃, with high-temperature exposure time controlled within 10 seconds to avoid internal chip damage.
- Polarity Identification The back marking A indicates the anode, and C indicates the cathode. Reverse connection will result in no light output.
- Circuit Drive Suggestion Configure proper current-limiting design according to the red light and infrared light chip paths to control brightness and prevent current overload.
- Moisture-Proof Storage The SMD LEDs are supplied in moisture-proof vacuum packaging. After opening, mounting is recommended within 24 hours. Long-term storage should be sealed and moisture-proof to prevent pad oxidation.
