1. 905nm 5W 3030 Multi-Junction VCSEL SMD for Pulsed Source Development
The 905nm 5W 3030 Multi-Junction VCSEL SMD is a compact surface-mount near-infrared source designed for nanosecond-pulsed sensing, direct time-of-flight evaluation, laser rangefinding, PCB integration and custom optical-transmitter development.
At a specified drive current of 1A, a temperature of 25°C, a pulse width of 100ns and a 0.1% duty cycle, the device provides:
- 4W minimum optical output
- 5W typical optical output
- 5W maximum specified optical output
The product provides a typical peak wavelength of 905nm within a specified wavelength range of 899–911nm.
Its beam divergence is specified as 20° using the D86 measurement definition.
The D86 value should not be interpreted as an FWHM or 1/e² beam-divergence value.
The compact 3030 SMD package supports direct PCB placement, automated SMT assembly, reflow soldering and application-specific optical integration.
Development directions include:
- Direct time-of-flight evaluation
- Compact laser rangefinding
- LiDAR transmitter evaluation
- Industrial distance sensing
- Object and presence detection
- Nanosecond pulsed-source evaluation

2. Optical and Electrical Characteristics
The principal optical and electrical characteristics of the 905nm 5W 3030 Multi-Junction VCSEL SMD are shown below.
Parameter | Minimum | Typical | Maximum | Test Condition |
|---|---|---|---|---|
Peak Wavelength | 899nm | 905nm | 911nm | 25°C |
Optical Output Power | 4W | 5W | 5W | IF = 1A |
Threshold Current | — | 10mA | — | — |
Forward Voltage | — | 20V | — | IF = 1A |
Beam Divergence, D86 | — | 20° | — | D86 |
The optical-output values are specified at 25°C using a 100ns pulse width and 0.1% duty cycle.
This product should not be interpreted as a continuous-wave device. The 5W typical optical-output value applies only under the specified short-pulse test conditions.
Performance in the completed assembly may also be influenced by:
- Pulse-current waveform
- Driver rise and fall time
- Voltage and current overshoot
- Repetition rate
- PCB trace inductance
- Package parasitics
- Solder-joint quality
- Device temperature
- External optical structure
The 20° beam-divergence value uses the D86 definition and should not be replaced by an FWHM or 1/e² value.
The device should therefore be evaluated using the intended driver, PCB, package environment and optical assembly.
3. 3030 SMD Package and SMT Integration
The device uses a compact 3030 surface-mount package for PCB-level integration.
Package Parameter | Specification |
|---|---|

The package supports:
- Automated pick-and-place assembly
- SMT production
- Reflow soldering
- Compact PCB layouts
- Low-profile optical transmitters
- Lens or diffuser integration
- Repeatable component positioning
- Scalable volume assembly
PCB and assembly development should consider:
- Recommended pad geometry
- Package polarity
- Current-path resistance
- PCB trace inductance
- Driver-to-package distance
- Solder-paste volume
- Reflow profile
- Optical-axis alignment
- ESD protection
The corresponding datasheet specifies that reflow soldering should be performed only once.
Pressure should not be applied to the optical package during reflow or after the soldering process.
The device is ESD-sensitive. Appropriate electrostatic-control procedures are required throughout storage, placement, assembly, testing and handling.
4. Application Development
The 905nm 5W 3030 Multi-Junction VCSEL SMD is intended for compact pulsed near-infrared transmitter projects requiring a completed SMD package, 20° D86 beam divergence and a specified 1A pulse current.
Application directions include:
- Direct time-of-flight evaluation
- Compact laser rangefinding
- LiDAR transmitter evaluation
- Industrial distance sensing
- Object detection
- Presence and proximity sensing
- Optical timing and trigger systems
- PCB-level pulsed sources
- Compact optical modules
- Engineering and laboratory evaluation
dToF and Laser-Rangefinding Development
For dToF and laser-rangefinding applications, product selection should consider working distance, receiver sensitivity, detector timing, target reflectivity, optical transmission, D86 beam divergence, pulse width, repetition rate and external optical structure.
The 3030 package supports compact transmitter layouts where PCB space and device height are important.
The 20° D86 beam divergence provides the specified unshaped optical field before an external lens, diffuser or collimator is applied.
The 100ns pulse condition is longer than the 5ns condition used by the 70W model. Driver and receiver timing should therefore be evaluated according to the customer’s complete measurement architecture.
Final working distance cannot be determined from VCSEL optical-output power alone.
It also depends on the transmitter, receiver, optics, signal-processing system, target conditions and operating environment.
For LiDAR, dToF and laser-rangefinding projects, product selection should consider peak optical output, pulse width, repetition rate, receiver sensitivity, detector timing, target reflectivity, optical transmission and the required field of view.
The VCSEL bare die is one component of the complete transmitter system. Final detection distance and system performance depend on the driver, package, optics, receiver, signal processing and environmental conditions.

For broader high-power NIR packaging, thermal-path and optical-module development, visit the High-Power NIR & Optical Modules solution page.
PCB and Optical-Module Development
The surface-mount package allows PCB and optical-module developers to integrate the VCSEL using automated placement and reflow production.
Possible integration directions include:
- Compact dToF transmitters
- PCB-level rangefinding sources
- Lens-integrated VCSEL SMD assemblies
- Diffuser-integrated pulsed sources
- Collimated optical transmitters
- Industrial optical-source boards
- Application-specific sensing modules
The final optical field depends on the 20° D86 beam-divergence value, package placement, optical-axis alignment, lens focal length, lens-to-package spacing, diffuser characteristics, PCB tolerance and mechanical structure.
The component does not independently establish the eye-safety classification, detection distance or regulatory status of the customer’s completed system.
