1. 660nm 5mW VCSEL Laser Diode in a Hermetic 3-Lead TO-46 Package for Compact Red-Laser Integration
This 660nm 5mW VCSEL laser diode is a hermetically sealed, three-lead TO-46 component for compact OEM red-laser integration. At a 25°C laser temperature and 10mA drive current, the source specifies 4mW minimum and 5mW typical optical output power, with a 650nm / 660nm / 670nm wavelength range stated as minimum / typical / maximum.
The standard device uses a specified window cap on a hermetic 3-lead TO-46 header. It gives engineering teams a compact packaged VCSEL option when the wavelength, optical-output test point, CW operating direction and TO-can integration path must be evaluated together.
2. 660nm Wavelength, 5mW Output and CW Operating Characteristics
The source characterizes the device at 25°C. At 10mA, the specified center wavelength is 660nm typical, the optical output power is 5mW typical, and the laser forward voltage is 2.8V typical. Threshold current is 3.5mA typical, with a stated 2.5mA minimum and 4.5mA maximum range.
The maximum CW forward-current rating is 15mA. This absolute maximum is not a normal operating recommendation: optical output, forward voltage, wavelength and thermal behavior should be reviewed at the intended project drive condition.
3. Hermetic 3-Lead TO-46 Package and Electrical Interface
The standard configuration is a hermetic 3-lead TO-46 VCSEL package with a specified window cap. The release drawing provides the mechanical and lead arrangement needed for initial mounting, electrical-interface and optical-path review.
The package is not a generic two-lead laser diode. Before final integration, confirm the target pin assignment, lead form, window-cap requirement, optical alignment, PCB or flex connection, and qualification conditions for the intended assembly.
4. Compact Red-Laser Integration and Custom TO-52 Configuration Options
The source identifies laser-assisted auto-focus and ranging, video-focus tracking assistance for AR/VR, and 3D-sensing development as component-level application directions. Final optical performance, safety and regulatory status remain properties of the completed OEM system.
For a cost-conscious OEM redesign program, this low-power 660nm VCSEL configuration can be assessed as a custom alternative for legacy TO-52 edge-emitting-laser integration. A TO-52 mechanical configuration may be evaluated where appropriate, but it is not a standard stocked package or a direct drop-in replacement: electrical drive, pin assignment, optical coupling and system performance must be confirmed for each project.
5. Evaluation, Documentation and Custom Development Support
For qualified component-level evaluation, a 10 pcs / KIT sample path can be discussed together with the datasheet and the source-backed optical and electrical test conditions. Package configuration, intended operating point and integration requirements should be confirmed before a final production configuration is selected.
For component-level project evaluation, an Initial Product Report covering the Laser Diode Series and VCSEL Laser Diode Chip Series has been filed with the U.S. FDA CDRH. This filing supports technical documentation and product evaluation.
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.
6. Frequently Asked Questions
FAQ 1. Is This 660nm 5mW VCSEL Rated for Continuous-Wave Operation?
The source lists CW forward current with a 15mA maximum rating. The published optical-output, wavelength and voltage figures on this page are stated at 10mA and 25°C; evaluate the intended operating condition rather than treating the maximum rating as a normal setpoint.
FAQ 2. Can This 3-Lead TO-46 VCSEL Be Supplied in a TO-52 Package?
The standard released package is a hermetic 3-lead TO-46 configuration. A TO-52 mechanical configuration can be assessed as a custom project, but compatibility is not automatic. Confirm the mechanical envelope, electrical drive, pin assignment, optical coupling and final system requirements before selection.
FAQ 3. Which Applications Can Be Evaluated with This 660nm TO-46 VCSEL?
The release source identifies laser-assisted auto-focus and ranging, video focus tracking assistance for AR/VR, and 3D-sensing development. These are component-level evaluation directions; the OEM must validate the final device's optical performance, safety and regulatory requirements.
