Sigetronics successfully completed the in-orbit validation of its Schottky Barrier Diode (SBD) by participating in the Korea Aerospace Research Institute (KARI)'s "Domestic Space Qualification Platform No. 1" program. The device operated reliably for more than six months in the actual space environment, further demonstrating the reliability and robustness of Korea's domestically developed semiconductor technology.

The Domestic Space Qualification Platform No. 1 was a national project conducted to verify the performance and reliability of domestically developed electronic components under actual space conditions. A total of nine key categories of Korean electronic components—including SRAM, ADC/DAC, diodes, capacitors, resistors, magnetic cores, thermistors, heaters, and connectors—were integrated into a satellite, and their performance was successfully validated in orbit.

Sigetronics' Schottky Barrier Diode (SBD) operated normally throughout more than six months of in-orbit operation. Measurement data confirmed stable electrical performance with no signs of degradation or abnormal behavior. The minor variations observed were attributed to satellite temperature fluctuations and measurement noise, with no evidence of any functional failure or performance degradation of the device itself.

This achievement demonstrates that Sigetronics' semiconductor devices have secured outstanding reliability even under actual space conditions. It represents a significant milestone that further expands the potential application of the company's technologies not only in the aerospace sector but also across a wide range of industries requiring high-reliability semiconductor solutions.

Leveraging its in-house semiconductor manufacturing technology and robust quality management capabilities, Sigetronics will continue to expand its portfolio of high-reliability semiconductor solutions beyond the automotive, industrial, and defense markets into the space industry.
