Solitron Devices, Inc., a Delaware corporation, designs, develops, manufactures, and markets solid-state semiconductor components and related devices primarily for the military and aerospace markets. The company produces a broad range of products including bipolar and MOS power transistors, power and control hybrids, junction and power MOSFETs, field effect transistors, and other related semiconductor devices. These products are used in defense, aerospace, and industrial applications such as radar systems, missile control, satellites, and power distribution systems. Solitron operates manufacturing facilities in West Palm Beach and Apopka, Florida, and maintains certifications under MIL-PRF-19500, MIL-PRF-38534 Class H, AS9100, and ISO 9001 standards to qualify its products for U. S. government and defense contractor supply chains.

The company generates revenue through the sale of its semiconductor components and hybrid circuits, which are either custom-designed to meet specific customer requirements or offered as standard catalog items. Revenue is derived from products such as power transistors, power MOSFETs, hybrids, field effect transistors, and wafers/dice, with custom products accounting for approximately 96% of sales in the fiscal year ended February 28, 2025. Sales are primarily made to customers whose end products are sold to the United States government, as well as to defense contractors and industrial users. The company’s revenue mix varies based on defense contract awards, congressional appropriations, and shifts in technology demand, with product line contributions fluctuating year to year.

The company operates through the following segments:

• Power Transistors. This segment includes the design, manufacture, and sale of bipolar power transistors and power diodes used for high-current and high-voltage control applications in electronic circuits. The company manufactures over 500 types of power bipolar transistors using more than 60 silicon chip types, serving applications requiring currents from 0.1A to 300A and voltages from 30V to 1000V. Products are available in both standard and custom configurations and are qualified under MIL-PRF-19500 standards for military use.

• Power and Control Hybrids. This segment involves the production of thick film hybrid circuits that integrate passive and active components such as semiconductor chips, capacitors, and resistors on ceramic substrates. These high-reliability devices are custom-manufactured for military and aerospace systems and include products like power amplifiers, voltage regulators, and motor controllers. The company has been certified under MIL-PRF-38534 Class H since 1990 and qualified since 1995, ensuring compliance with defense industry quality and reliability standards.

• Junction and Power MOSFETs. This segment covers metal-oxide-semiconductor field-effect transistors used for switching and amplification in power management circuits. The company manufactures both N-channel and P-channel MOSFETs, expanding this line in response to customer demand for high-voltage, high-current, and fast-switching devices. These components are offered in standard and custom forms and are used in applications requiring thermal stability and resistance to secondary breakdown.

• Field Effect Transistors. This segment includes junction field-effect transistors (JFETs) used for signal processing and switching in analog circuits. The company produces about 30 different JFET chip types, which are used to create over 350 discrete field effect transistor variants. Most conform to standard 2N designation standards and are available as both catalog and custom products. The company continues to expand this product line based on evolving customer needs.

• Wafers and Dice. This segment involves the sale of unfinished silicon wafers and individual semiconductor chips (dice) to other manufacturers for further processing or integration into hybrid circuits. While representing a small portion of total sales (1% in FY 2025), this activity supports the company’s broader semiconductor manufacturing capabilities and supply chain flexibility.

Solitron Devices holds a niche position in the defense and aerospace semiconductor market, where it competes on product reliability, performance, and customer service rather than price alone. The company benefits from long-standing qualifications under military standards such as MIL-PRF-19500 and MIL-PRF-38534 Class H, which are prerequisites for supplying components to U. S. defense programs. While the broader electronic component industry faces intense price erosion and foreign competition, Solitron operates in a segment where technological change is gradual and barriers to entry are high due to certification requirements. Key competitors in the military and aerospace markets include Infineon Technologies, Microsemi Corporation, Anaren Inc., NEOTech, and Sensitron Semiconductor. The company’s competitive advantages stem from its decades of experience, proprietary manufacturing expertise, experienced engineering staff, and ability to deliver high-quality custom hybrids on short lead times.

The company’s customer base consists primarily of defense contractors, aerospace manufacturers, and industrial firms whose products are sold to the U. S. government or used in military and aerospace applications. Major customers include RTX Corporation (formerly Raytheon Technologies Corporation), which accounted for 31% of net sales in the fiscal year ended February 28, 2025, and ConMed Linvatec, which represented 38% of sales in the same period. Other significant customers have included L3Harris Technologies, General Electric Aviation, Honeywell International, and Northrop Grumman Systems Corporation. Standard and catalog products are also sold to the broader electronic industry and distributors, though these represent a small fraction of total sales. Sales to foreign customers account for less than 1% of revenue, with all transactions conducted in U. S. dollars. The company experiences significant customer concentration, with a small number of clients typically representing a large percentage of annual sales.
