1. 780nm 5mW 3030 VCSEL SMD for Compact PCB Optical Integration
The 780nm 5mW 3030 VCSEL SMD is a multimode near-infrared surface-mount laser diode for compact PCB optical sources, sensing modules and application-specific OEM optical-system integration.
At CW 7mA and a 50°C heat-sink temperature, the device provides 5mW typical optical output within a specified 4mW to 6mW range. Its peak wavelength is 780nm typical within a 772nm to 788nm range, and its beam full divergence is 23° typical within a 20° to 26° D86 range.
The 3030 SMD package supports automated placement and compact board layouts. The published electro-optical characteristics are specified under CW operation; the typical L-I-V curves also show QCW behavior at 25°C, 50°C and 85°C for engineering comparison.
Choose this model when the project requires:
- 780nm typical peak wavelength
- 5mW typical CW optical output
- A 7mA typical operating-current point
- A 3030 surface-mount footprint
- 23° typical D86 beam divergence
- PCB-level laser-source integration

2. Optical and Electrical Characteristics
The following values are taken from the released 780nm 5mW 3030 VCSEL SMD datasheet. The electro-optical table is specified under CW operation at a 50°C heat-sink temperature.
Parameter | Minimum | Typical | Maximum | Test Condition |

The 5mW optical-output value, 7mA operating-current value and 780nm wavelength value belong to the same CW 50°C test condition. System design should preserve that condition when comparing this device with another wavelength, package or power class.
The absolute maximum ratings specify an operating-temperature range of −20°C to 85°C and a storage-temperature range of −40°C to 120°C. These are limits rather than recommended design points; driver, PCB and thermal design must keep the device within validated operating conditions.
3. 3030 Package and SMT Integration
The device uses a 3030 SMD package with a nominal 3.0 × 3.0mm footprint and 0.6mm package height. The released package drawing identifies Pin 1 as cathode/negative and Pin 2 as anode/positive and shows the integrated protection-diode configuration.
PCB and production integration should account for:
- The released land pattern and pin polarity
- Optical-axis position and clearance above the emitting area
- Solder-paste design and the selected reflow profile
- ESD controls during storage, handling and assembly
- The local PCB thermal path under CW operation
- Lens, window or diffuser position relative to the optical axis
The 808nm 5mW 3030 VCSEL SMD provides an adjacent-wavelength 3030 option when the optical system requires an 808nm rather than 780nm source. Final selection should follow the receiver response, optical path and wavelength requirement of the complete system.
4. Product Selection and Application Integration
This model is the 5mW 3030 option within the current 780nm surface-mount family. It is intended for projects that prioritize a low-current CW source, a compact surface-mount package and a 780nm optical channel.
Compact NIR Sensing and Optical Measurement
The 780nm output supports component-level development of compact reflective sensing, optical detection, alignment and measurement modules when the detector response and optical path are matched to this wavelength. Working distance, target reflectivity, ambient light, receiver sensitivity and downstream optics determine the completed system performance.
Multi-Wavelength Red and Near-Infrared Optical Systems
The device also provides a 780nm channel for red and near-infrared multi-wavelength optical assemblies used in personal-care, photobiomodulation-device and other OEM optical-platform development. The VCSEL is a component-level light source; medical, beauty, veterinary or therapeutic claims must be established by the finished-device manufacturer under the applicable system, safety and regulatory requirements.
