1. 808nm 10mW 2835 VCSEL SMD for PCB Integration
The 808nm 10mW 2835 VCSEL SMD is a compact near-infrared VCSEL device supplied in a 2835 surface-mount package. It provides a typical peak wavelength of 808nm and a typical optical output power of 10mW.
This 10mW 808nm VCSEL diode is specified for Pulse / QCW operation. At a forward current of 15mA, with a 0.5ms pulse width and 10% duty cycle, the device provides 10mW typical optical output and up to 15mW maximum optical output.
Compared with an unpackaged VCSEL bare die, the 2835 VCSEL package has already completed the die-packaging process. It can be used for SMT placement, reflow soldering and PCB-level optical-source integration without requiring the customer to perform die attach and gold wire bonding.
The device can support compact near-infrared sources, PCB-level optical assemblies, sensing, machine-vision support illumination, industrial optical detection, beauty and personal-care equipment light-source development, and engineering prototype validation.
The 2835 package dimensions, electrode orientation, PCB pad design and assembly conditions should be confirmed using the corresponding product datasheet and package drawing. The device is ESD-sensitive and requires appropriate electrostatic protection during storage, handling, placement and testing.
2. Optical and Electrical Characteristics
The principal optical and electrical characteristics of the 808nm 10mW 2835 VCSEL SMD are shown below.
Parameter | Minimum | Typical | Maximum | Test Condition |
|---|---|---|---|---|
Peak Wavelength | 800nm | 808nm | 816nm | — |
Optical Output Power | — | 10mW | 15mW | IF = 15mA, QCW, 0.5ms pulse width, 10% duty cycle |
Threshold Current | — | 4.5mA | — | — |
Forward Voltage | — | 2.3V | — | IF = 15mA |
Beam Divergence, D86 | — | 21° | — | D86 |
Slope Efficiency | — | 1W/A | — | — |
Series Resistance | — | 50Ω | — | — |
Wavelength Temperature Shift | — | 0.047nm/°C | — | — |
The values above are representative parameters from the current product specification. Exact minimum, typical and maximum values, test conditions and tolerances should be confirmed in the corresponding product datasheet.
Beam divergence is specified using the D86 definition and should not be directly replaced by an FWHM or another beam-angle definition.
This device is specified for Pulse / QCW operation and should not be interpreted as a continuous-wave product. Performance in the final PCB assembly will also depend on drive current, pulse width, duty cycle, PCB thermal design and the external optical structure.
3. 2835 Package and SMT Integration
The 808nm 10mW VCSEL uses a 2835 surface-mount package for automated placement, reflow-soldering assembly and PCB-level near-infrared optical-source integration.
The packaged configuration reduces the development work associated with bare-die mounting, gold wire bonding and package protection. It is suitable for projects requiring a completed surface-mount VCSEL for direct PCB assembly.
Integration directions include:
- Automated SMT placement
- Reflow-soldering assembly
- Compact PCB optical-source layouts
- Single-device near-infrared sources
- Multi-device PCB optical arrays
- Sensing and detection circuit integration
- Beauty and personal-care equipment light-source assemblies
- Engineering prototypes and small-batch validation
PCB pad dimensions, device polarity, placement orientation and package dimensions should follow the corresponding 2835 package drawing.
The reflow profile, PCB material, copper-layer design and thermal conditions around the device should be confirmed according to the customer’s production process. A specific reflow-temperature profile should not be assumed without reference to the corresponding assembly documentation.
The standard reel quantity is:
- 4000 pcs / reel
