1. Standard 780nm VCSEL SMD Series
The 780nm VCSEL SMD Series is a near-infrared surface-mount laser diode series designed for direct PCB assembly through standard SMT and reflow-soldering processes.
The series provides 5mW and 10mW output-power classes with 2121 and 2835 package options. The 5mW version is available in a 2835 package, while the 10mW version is available in either 2121 or 2835 package.
These 780nm VCSEL devices use a multi-mode surface-emitting structure and operate in CW mode. The series is suitable for compact NIR sensing, PCB-level optical-source integration and OEM optical-device development. It can also be used as an auxiliary NIR wavelength in red + near-infrared multiwavelength products for beauty-device, hair-growth, veterinary PBM and neuro-PBM related device development.
Unlike VCSEL bare die products, this series is supplied as packaged VCSEL SMD components. It is suitable for product designers, PCB engineers, OEM/ODM device teams and optical-module developers who need a ready-to-mount near-infrared VCSEL package.
2. Detailed Optical and Electrical Characteristics
The 780nm VCSEL SMD Series combines low driving current, compact surface-mount construction and two package-size options. Output power, operating current, voltage and divergence angle vary by model. Selection should be based on the PCB design, driving condition, package footprint and target optical performance.

The 2121 package is suitable for compact designs with strict PCB-area and product-thickness limits.
The 2835 package is suitable for standard automated placement, general optical-source layouts and designs that require a larger SMD footprint.
Electrode configuration, dimensional tolerances and reflow-soldering conditions should be confirmed using the corresponding datasheet.
Other wavelength, power-bin or package requirements can be discussed according to the customer’s PCB structure and product-assembly requirements.
3. 780nm VCSEL SMD as an Alternative to Conventional TO-can Packages
Compared with conventional 780nm laser diodes in TO-can through-hole packages, the VCSEL SMD format can reduce component height and support automated PCB assembly.
The SMD laser-diode format is compatible with conventional pick-and-place equipment and standard SMT production processes. It can reduce manual insertion, lead handling and hand-soldering steps.
In suitable product designs, 780nm VCSEL SMD can help:
- Reduce the overall height of the laser and PCB assembly
- Simplify PCB layout and mechanical product design
- Support automated placement and batch reflow soldering
- Reduce manual soldering and through-hole insertion steps
- Lower assembly and processing costs
- Improve batch-production consistency
- Support compact multi-source PCB layouts
- Shorten small-batch validation and mass-production preparation
This series can be used as an alternative option for selected projects that are still using conventional 780nm TO-can or leaded laser-diode packages.
Whether it can be directly replaced should be verified against operating current, forward voltage, electrical polarity, optical output power, beam profile, divergence angle, thermal conditions and mechanical structure.
4. 780nm Applications
The 780nm wavelength is within the near-infrared spectrum and can be used as a component-level light source for compact sensing, PCB-level NIR source integration and auxiliary NIR wavelength design in red + near-infrared multiwavelength systems.
Compact NIR Sensing Devices
- Compact optical sensing modules
- Low-power NIR source testing
- PCB-level sensing assemblies
- Short-distance optical detection systems
- OEM optical-device prototypes
Beauty and Personal-Care Devices
- Beauty-mask light-source development
- Handheld beauty-device light-source boards
- Local personal-care devices
- Red + near-infrared multiwavelength product design
- Compact wearable optical products
In beauty and personal-care products, 780nm is more suitable as a near-infrared supplementary wavelength or auxiliary NIR source in a multiwavelength design, rather than replacing the main red-light wavelength.
Hair-Growth and Scalp-Care Devices
- Hair-growth caps
- Hair-growth helmets
- Hair-growth combs
- Hair-growth bands
- Scalp-care device development
- Multi-point NIR source layouts for wearable scalp products
In hair-growth and scalp-care devices, 780nm can be used as an auxiliary NIR wavelength in red + near-infrared combination designs for optical-source layout and multi-point package design.
Veterinary and Animal-Care Devices
- Pet PBM device development
- Canine and feline rehabilitation equipment
- Equine joint, tendon and soft-tissue rehabilitation-device development
- Red + near-infrared multiwavelength veterinary PBM systems
- Large-area optical-source layouts for animal-care equipment
In veterinary PBM or animal-care equipment, 780nm can be used as an auxiliary near-infrared source in multiwavelength systems. Final equipment should still be verified according to optical power density, working distance, thermal design and system safety.
Neuro-PBM and Research Devices
- Neuro-photobiomodulation research equipment
- Red + near-infrared PBM research-device development
- Helmet-type optical-source layouts for research devices
- Wearable optical-source layouts for research systems
- Multiwavelength optical layouts for experimental PBM systems
Neuro-PBM related content refers only to research-device development and component-level light-source selection. It does not indicate that the VCSEL component itself can treat disease or produce a confirmed clinical outcome.
For beauty, hair-growth, veterinary, joint, deeper-tissue or neuro-PBM applications, the complete device may require red and near-infrared wavelength combinations, optical power-density calculation, dose control, working-distance validation and thermal-design verification. Final device performance must be validated by the equipment manufacturer.
5. Evaluation Kit and Documentation Support
The 780nm VCSEL SMD Evaluation Kit supports early-stage verification of package options, PCB layouts and production processes.
The Evaluation Kit normally includes:

For applicable products, CE, EMC, EN 60825, LVD, RoHS, REACH and halogen-free certification and compliance documents are available. Documentation depends on the corresponding product model and does not represent certification of the customer’s finished device.
The following parameters can be discussed for specific projects:
- Center wavelength
- Wavelength tolerance
- Optical output power
- Power-bin selection
- Package dimensions
- PCB assembly and optical layout requirements
6. Frequently Asked Questions
FAQ 1. How should I choose between the 5mW and 10mW 780nm VCSEL SMD options?
The 5mW 2835 version is suitable for lower-power NIR source integration and standard PCB assembly. The 10mW version is suitable when higher single-point output power is required.
The 10mW version can be selected in either 2121 or 2835 package. The 2121 package is suitable for more compact PCB layouts, while the 2835 package is suitable for standard SMT production and designs that prefer a larger package footprint.
Final selection should consider target optical output, available PCB area, working distance, operating current, thermal path and required package size.
FAQ 2. Can 780nm VCSEL SMD replace a conventional 780nm TO-can laser diode?
780nm VCSEL SMD can be used as an alternative option for selected TO-can or leaded laser-diode projects, but it should not be assumed to be a direct drop-in replacement.
Replacement review should verify operating current, forward voltage, electrical polarity, optical output power, center wavelength, beam divergence, package dimensions, PCB pad design, reflow-soldering process and thermal path.
FAQ 3. Can 780nm VCSEL SMD be used in beauty, hair-growth, veterinary or neuro-PBM devices?
Yes. 780nm VCSEL SMD can be used as a near-infrared component-level light source for beauty-device development, hair-growth products, veterinary PBM equipment and neuro-PBM research-device development.
In these applications, 780nm is more suitable as an auxiliary NIR wavelength in red + near-infrared multiwavelength designs. The complete system must be validated by the equipment manufacturer according to optical output, dose design, driving condition, working distance, safety design, thermal design and applicable market regulations. The VCSEL component itself does not represent a medical effect or treatment conclusion.
