1. 660nm 5mW VCSEL Bare Die for Three-Emitter Red Optical-Source Development
The 660nm 5mW VCSEL Bare Die is a three-emitter, multi-mode visible-red chip for custom laser packaging, wire bonding, ceramic-submount assembly and compact OEM optical-source development. The source datasheet lists 4.0mW minimum and 5.0mW typical optical output at 10mA and 25 °C QCW.
As an unpackaged semiconductor die, it requires a customer-selected package, electrical drive, thermal path, lens or beam-shaping approach and complete finished-device validation.
Lead Time: In-stock products are dispatched within 3 business days; custom-packaged products have a lead time of 15–20 days.
MOQ: The minimum order quantity is 1 reel; selected special models support small-batch orders.
2. Source-Specified Optical and Electrical Characteristics
At the stated 10mA, 25 °C QCW condition, the source lists 660nm typical center wavelength, 4.0mA typical threshold current, 2.6V typical forward voltage and 19° typical divergence.
The source specifies a 200±10μm x 200±10μm die, 125±5μm die thickness, 88±3μm x 88±3μm bond pads and a 200±10μm x 200±10μm back electrode.
3. Bare-Die Assembly and Packaging Direction
The three-emitter configuration and symmetric donut-shaped source far field should be assessed with the selected die-attach process, bonding layout, optics, working distance, pulse drive and thermal design.

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.
5. Frequently Asked Questions
FAQ 1. What output is specified for this 660nm 5mW VCSEL bare die?
The source lists 4.0mW minimum and 5.0mW typical optical output at 10mA and 25 °C QCW. Integration conditions determine finished-module output.
FAQ 2. How many emitters are specified for this die?
The product specification identifies three emitters. The final optical result still depends on packaging, optics, alignment, drive and thermal conditions.
FAQ 3. When should an SMD option be considered instead of a bare die?
A bare die is appropriate when the customer controls packaging and optical integration. A packaged SMD is the appropriate option when PCB-level assembly is the required form factor.
