SMD PD Receiver Tube for Pulse Oximeter Probe Applications
A miniature square SMD photodiode receiver designed for pulse oximeter probes, fingertip SpO₂ meters, wearable health monitoring devices, and precision optical transmission detection modules.
Product Overview
This SMD PD receiver tube is developed by Jiangmen Yiyang Infrared Semiconductor for pulse oximeter probes, fingertip pulse oximeters, and wearable health monitoring devices. It adopts a miniature square surface-mount package with a built-in large-area square photosensitive chip. The black filtered epoxy housing helps block ambient stray light interference, while its spectral response is well matched with 660nm red light and 905nm infrared dual-wavelength emitters, forming a complete pulse oximeter transmission detection module. With standard two-pin gold-plated pads, it supports fully automatic SMT mounting and standard reflow soldering. Its compact size saves PCB space, while high photoelectric linearity and extremely low dark current make it a core sensing component for medical SpO₂ detection.

Black Filtered Package
The black light-shielding epoxy blocks indoor white light and outdoor strong light, helping prevent reading drift and measurement failure in complex lighting environments.
Miniature SMD Design
The compact and thin package greatly reduces PCB space compared with through-hole PD tubes, making it ideal for disposable probes, wristband SpO₂ modules, and slim fingertip oximeters.
Gold-Plated Pads for SMT Production
Thickened gold-plated pads resist oxidation and provide uniform solder paste adhesion, supporting high-yield reflow soldering and high-speed automatic SMT mounting.
Large Square Photosensitive Area
The customized square photosensitive chip provides uniform light receiving and strong consistency for red and infrared signals, improving SpO₂ and pulse detection accuracy.
Complete Matching Supply
It can be supplied together with the matching 2-pin SMD 660nm + 905nm dual-wavelength emitter, reducing component selection work and material management costs.
Medical-Grade Quality Control
Produced in a dust-free packaging workshop and fully inspected for photocurrent, dark current, and spectral response to ensure consistent batch performance.
Application Scenarios
- Medical SpO₂ Detection Devices Disposable pulse oximeter probes, fingertip pulse oximeters, monitor SpO₂ modules, and wearable pulse oxygen wristbands.
- Home Portable Health Instruments Mini fingertip SpO₂ meters, household pulse monitoring wristbands, and portable health monitoring devices.
- Optical Skin Detection Equipment Skin spectrum analyzers, vein imaging devices, and non-invasive optical detection modules.
- Transmission Optical Sensing Near-infrared material composition detection, bio-optical sampling, and compact transmission photoelectric sensors.
SMT Soldering & Usage Notes
- Reflow Temperature Control Recommended peak temperature should be ≤260℃, with high-temperature exposure time controlled within 10 seconds to avoid chip damage.
- Polarity Identification The back marking A indicates the anode, and C indicates the cathode. Reverse connection is not allowed.
- Optical Path Matching Use together with a 660nm + 905nm dual-wavelength SMD emitter and align the optical path to fully illuminate the photosensitive window.
- Moisture-Proof Storage Products are supplied in vacuum moisture-proof tape packaging. Mounting is recommended within 24 hours after opening. Long-term storage should remain sealed and moisture-proof.
