Solid State Devices Inc

Solid State Devices, Inc. (SSDI) is a JANS-certified and AS9100-registered manufacturer of high-power and high-voltage semiconductors and electronic assemblies for aerospace, defence, and space applications, headquartered in La Mirada, California. Founded in 1967, the company has over 55 years of experience pioneering hermetic semiconductor manufacturing and has earned a reputation for setting the highest standards of reliability, power density, and performance.

SSS pursues its '3H Products' philosophy — High Density, High Performance, High Reliability — continuously evaluating materials, processes, and package designs to reduce footprint and weight while leveraging the latest technology. Approximately 96% of SSDI's sales support Aerospace and Defence programs including satellites, manned spacecraft, launch vehicles, fixed-wing military aircraft, rotorcraft, and maritime/undersea systems.

SSSD holds a strategic market role by focusing on high-reliability (HiRel) products that competitors are unable or unwilling to supply, and by developing End of Life (EOL) and Diminishing Manufacturing Sources (DMS) solutions when other manufacturers obsolete products. Notable space programme contributions include the NASA Artemis II mission — where SSDI components flew on both the Orion spacecraft and SLS launch vehicle, travelling over 248,000 miles from Earth — including rectifiers, Schottky diodes, SiC MOSFETs, Zener diodes, TVS devices, and radiation detector PIN diodes.

SSSD's product portfolio spans 16 categories: rectifiers, Schottkys and SiC Schottkys, bridge rectifiers, Zeners, TVS devices, Thyristors/SCRs, SiC MOSFETs, JFETs, IGBTs, Gallium Nitride (GaN) Power FETs, transistors, IC/voltage regulators, power modules, power hybrids, high-voltage assemblies, and specialty radiation detector PIN diodes. The company operates three facilities in La Mirada — a JANS-certified main manufacturing and test facility, a JANS-certified wafer fabrication facility, and an administration building — and holds ISO 9001, AS9100, and DLA JANS certification.
