Semicoa -
Precision Power for the Harshest Frontiers

When failure isn't an option, engineers turn to Semicoa—a trusted name in high-reliability semiconductors built for the unforgiving demands of military, aerospace, and space missions.

Armed with the industry’s most comprehensive portfolio of small signal, RF small signal, and power bipolar transistors, Semicoa delivers unmatched performance where every nanosecond and every milliamp counts.

At the heart ofg our innovation is our elite Radiation Hardness Assurance (RHA) Program—a gold standard for consistency and quality. Our proprietary Rad Hard By Design bipolar transistor technology is engineered to withstand 300 Krad (Si) total dose minimum, offering extraordinary wafer-to-wafer and lot-to-lot uniformity.

For engineers designing in the most extreme radiation environments, Semicoa means reliability, repeatability, and rock-solid performance—no compromises.

Authorized Supplier…

ES Components is a leading franchised distributor for SEMICOA standard, JANHC, and JANKC bipolar transistors and diodes for high-reliability applications in defense, military, aerospace, and space markets. We offer a wide range of military-grade versions of Fairchild's bipolar transistors, including discontinued products, to meet the specific requirements of these industries.

Quality and high reliability are the cornerstones that military, aerospace and space applications are built upon. In many instances, there’s absolutely no room for error. Semicoa has the most stringent Radiation Hardness Assurance Program (RHA) in the semiconductor market and has set the benchmark for qualifying RHA devices. We offer the largest selection of small signal, RF small signal and power transistors for demanding military, space and high reliability industrial applications. All devices are hermetically sealed in metal cans or ceramic packages. All products are also available in die form for hybrid circuit applications.
Devices as specified by Source Controlled Documents (SCD) are manufactured, screened and tested to customer requirements as specified in the SCD. The SCD product may be direct derivatives of existing MIL-PRF-19500 devices on which SEMICOA already holds qualification, or they may be custom designed devices. They may be a blend of our total device and package capabilities including die and packages that are not part of our standard Qualified Parts List (QPL) offering.
Semicoa has developed a Rad Hard By Design Bipolar Transistor Technology that can be applied to either NPN or PNP devices to improve the total dose hardness of the device to a minimum of 300 Krad with excellent wafer-to-wafer and lot-to-lot uniformity.
Semicoa has introduced all of its Rad Hard Bipolar Transistors at JANTXV Quality Level plus the guarantee of radiation hardness. Due to the enhanced methodology used by Semicoa to qualify RHA products, all RHA devices qualified for JANS are also qualified for JANTXV in accordance with MIL-PRF-19500. Currently Semicoa has 16 unique devices listed on the QPL at this quality level plus radiation hardness and plans to add the remaining 26 devices to the QPL by the end of the year.
