Semicoa Semiconductors

Semicoa designs, develops, and manufactures semiconductors for military, defense, aerospace, and space applications. It offers small signal, RF small signal, and power transistors that are available in die form for hybrid circuit applications. Electronic applications in defense, aerospace, and space markets require greater levels of performance and reliability than conventional semiconductors can support.


Semicoa offers high-reliability semiconductors and services that conform to the exacting quality levels of MIL-PRF-19500. Semicoa has the most stringent Radiation Hardness Assurance Program (RHA) in the semiconductor market and has set the benchmark for qualifying RHA devices. Semicoa offers 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 Semicoa’s total device and package capabilities including die and packages that are not part of Semicoa’s 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.


Semicoa is now offering Surface Mount, Low Dose Rate (LDR) Total Dose qualified Bipolar Transistors tested at 10 mrad/s and characterized for the effects of displacement damage. SEMICOA Corporation was founded in 1968 and is based in Costa Mesa, California.
