DIP 660nm Red Light + 905nm Near-Infrared Dual-Wavelength Emitter
A square flat-top through-hole dual-wavelength emitting diode developed for pulse oximeter probes, fingertip pulse oximeters, wearable SpO₂ modules, and optical sensing applications.
Product Overview
This DIP dual-wavelength emitting diode is developed and packaged by Jiangmen Yiyang Infrared Semiconductor for pulse oximeter probes and fingertip pulse oximeters. A single device integrates a 660nm red light chip and a 905nm near-infrared chip inside a square flat-top transparent epoxy package. With a two-lead through-hole structure, it can be paired with the same series square PD receiver tube to form a complete pulse oximeter optical coupling module. The integrated dual-light source design eliminates the need for two separate LEDs, simplifies the internal structure of the probe, reduces size, and provides high wavelength consistency and uniform light intensity.

Integrated Dual-Wavelength Design
One component integrates both red and infrared light sources, saving narrow probe space, simplifying mold design and PCB wiring, and reducing material and assembly costs.
Parallel Narrow Optical Path
The square flat-top narrow-window package keeps the dual-chip optical paths parallel, helping light transmit vertically through the finger for improved sampling consistency.
High Wavelength Consistency
Chips are mounted and wire-bonded in a dust-free workshop, ensuring minimal red and infrared output differences within the same batch for stable oximeter readings.
Long Through-Hole Leads
Standard extended leads can be trimmed or bent as needed, supporting probe cable molding, through-hole soldering, and reliable assembly for oxygen sensor probes.
Full Customization Support
Red and infrared power ratio, total lead length, bent-lead shape, and epoxy color can be customized. Matching square PD receivers can be supplied as a complete set.
Factory Inspection Quality Control
Each product is tested for wavelength sorting, voltage, and light intensity before shipment, supporting low attenuation, long service life, and stable medical device operation.
Core Application Scenarios
- Medical Oxygen Detection Devices Fingertip pulse oximeters, wristband pulse oxygen modules, desktop monitoring SpO₂ probes, and disposable oxygen sensor probes.
- Home Portable Health Devices Household pulse detectors, wearable health bracelets, and mini fingertip oxygen monitors.
- Optical Skin Detection Instruments Skin spectrum detection instruments, vein imaging devices, and non-invasive optical therapy equipment.
- Transmission Optical Sensing Modules Near-infrared material detection, bio-optical sampling, and transmission photoelectric detection components.
Soldering & Usage Notes
- Soldering Standard Recommended soldering iron temperature should be ≤300℃, and each soldering time should be ≤3 seconds to avoid damaging the internal dual chips.
- Polarity Identification The two leads are common anode and common cathode structures. Reverse connection is not allowed.
- Circuit Drive Independent current-limiting resistors are recommended for the two chip paths to separately control red and infrared brightness and prevent overcurrent damage.
- Optical Path Matching Use together with the matching square PD receiver tube and ensure full alignment between the emitting and receiving windows for better sampling accuracy.
- Storage Environment Store in a dry, sealed, and light-proof environment to prevent lead oxidation and epoxy aging that may reduce light transmission.
