Seizing the Moment: Slkor Offers 20 Free Models to Accelerate Local Semiconductor Innovation

 


Figure 1: Slkor free sample list of 20 models

 

To help engineers and end-users speed up product development while cutting selection and validation costs, Slkor Semiconductor has launched a “Free Sample” campaign. This initiative includes 20 of our most popular models, covering thyristors (SCRs), gate driver ICs, logic-output optocouplers, DC-DC power chips, linear regulators, and MOSFETs.

All of these products are mass-market proven, offering mature and reliable solutions. They serve as drop-in alternatives to top-tier international brands like STMicroelectronics (ST), Texas Instruments (TI), Infineon, Broadcom, and ONsemi. Slkor’s components are already widely used across switching power supplies, motor drives, industrial automation, automotive electronics, communication equipment, and more.

Since its founding in 2015, Slkor has been deeply committed to advancing domestic semiconductor innovation, focusing on three major product lines: diodes & triodes, power devices, and power management ICs. Leveraging strong technical expertise, Slkor has launched over 2,000 semiconductor products and built competitive advantages across four key areas:

  • Solid Technical Strength – Core team members from Yonsei University (South Korea) and Tsinghua University excel in SiC MOSFET fabrication and 5th-generation ultra-fast recovery power diode technology.
  • Guaranteed Quality – Fully certified with California 65, ISO9001, RoHS, and REACH, ensuring a reliable and robust quality system.
  • Controllable Lead Times – As a local Chinese brand, Slkor provides stable production capacity, reliable supply, and cost advantages.
  • Smooth Replacement – Parameters align with leading imported brands; mass-production validation ensures stability, and technical support is available for seamless integration and debugging.

 


 

Building on these advantages, Slkor is now launching a "Free Sample" campaign to provide end customers with hands-on support, helping projects move forward faster. The campaign is live now, and our technical team is ready to assist with any questions during debugging.
