YINGHUA

YINGHUA 5V Laser Diode Dot Copper Semiconductor Tube 6MM

SKU CH-RV0H-NX26G

A 5 V copper-housed semiconductor laser tube with a 6 mm outer diameter that emits a focused dot beam

  • Product typeICs Semicoductors
  • 5 V operating voltage simplifies low-voltage driver design
  • Dot-pattern beam suits alignment and sensing tasks
  • Copper housing aids heat dissipation for stable output
  • 6 mm outer diameter fits compact module sockets

What it is and who it is for

The YINGHUA 5V laser diode emits a focused dot beam from a 6 mm copper semiconductor tube. It suits experimenters, educators and OEM integrators building low-voltage laser modules for alignment, sensing or demonstration purposes. The 5 V operating voltage allows direct connection to common logic-level power rails without additional regulation.

Sustained-load behaviour

Continuous operation at the rated 5 V keeps the copper housing warm but within normal semiconductor limits when adequate heat-sinking is provided. Without external thermal management the tube temperature will rise steadily, causing wavelength drift and reduced output stability over long runs. Users planning extended duty cycles must attach the module to a suitable heat spreader or forced-air path.

Questions about this item

How much heat does the 5 V laser diode generate when running continuously?

The 5 V laser diode produces heat proportional to its forward current and voltage drop; without a datasheet the exact thermal dissipation cannot be stated.

What driver or power supply must I already own to operate the 6 mm copper laser tube at 5 V?

You need a constant-current laser driver rated for 5 V output and the diode’s specified forward current, plus appropriate heat-sinking for the 6 mm copper housing.
