SMD LD-3433: Designed for automated machine mass production

July 12, 2022

The SMD LD-3433 of LECC technology is currently the smallest laser diode in the industry. We develop parts for surface- mount technology (SMD) to integrate laser diodes into a "compact" size of 3.4 x 3.3mm, effectively reduce the volume of packaged product’s weight only 0.01g and operation lifetime up to 11,000 hours!

Fast automated process, excellent heat dissipation performance, suitable for mass production of automated SMT machines, ideal for consumer healthcare applications such as low energy laser therapy, such as laser hair growth caps/combs, laser belts, UVC handheld germicidal lamps, etc. The SMD LD-3433 offers industry leading performance, reliability and cost of ownership.

LECC technology also provides TO or SMD packaged laser diodes. If customers have special requirements for other specifications, we can also provide customized services.


  • Integrates EEL into SMD package
  • Suitable for thin and compact designs
  • Zener diode is good for anti-static


  • Healthcare LLLT products
