• Portfolio Rationalization: Many OEMs have reduced their low volume offerings and continue to support the popular DO-35 and DO-41 packages. Vishay reported an expected revenue of $3.17 billion for 2024 (February 2025). Rationalization will increase reliance on major suppliers for second source and will be an advantage for the industry.
• Industrial Modernization: The current automation of factories has increased demand for simple overvoltage protection for various sensors, relays, and control boards. Siemens reported €75.9 billion for fiscal 2024 (December 2024), exemplifying the investment behind this equipment and the market. Through-hole devices retain their value when the importance of field replacement and mechanical durability overpotential outweighs board densification.
• Substitution Pressure: More integrated SMD designs are progressively displacing discrete through-hole designs and protection in new consumer products. In 2024, Texas Instruments reported $15.6 billion in revenue to demonstrate their commitment to providing more integrated power-management solutions that will support the ongoing industry trend. The market is therefore likely to shift towards legacy equipment, industrial repair, and cost-effective designs rather than more widespread market growth.

Though through-hole zener diode demand will continue to exist in places where serviceability, surge tolerance, and low price are priorities. Automotive electronics, industrial controls, and power supplies will set relevant design requirements. Price competition from SMD integrated protection devices and integrated protection solutions will be a concern for the suppliers until 2027; however, the suppliers who maintain legacy packages, provide second source, and retain qualification data are expected to maintain their market position.

Improved stability, leakage, surge tolerance, and operating temperature range of zener diodes offers better control of voltage references with improved transient suppression and protection against switching and signal regulation. Through-hole components will vastly improve precision and control of components in the above-mentioned circuits. 2025 was the year of increased adoption of better controlled voltage architectures in power systems, retaining use of control and protection circuits at 5V and 12V levels. For the next 3-5 years, additions of through-hole zener diodes will serve control circuits needing additional ruggedness at the cost of size.
• Automotive and Industrial: Increasing electrification requires more control modules, more sensors, battery-management, charging, and power conversion systems that provide voltage stabilization and protection. Through-hole components have great utility in rugged, prototyped, and field repairable control systems, industrial equipment, laboratory equipment, and high temperature systems that require mechanical strength and inspection access. 2025 had electric and hybrid vehicles incorporating many control functions at low voltage, alongside high voltage systems. In the next 3-5 years, factory automation, charging systems, renewable energy systems, and vehicle systems will increase application flexibility, but increased functionality will require greater qualification of components, as systems will be subject to more thermal and mechanical variation.
• Manufacturing and Cost Advantages: Mass production and assembly of through-hole zener diodes present advantages of low prices and ease of testing. Relative to surface mount technologies, simpler methods of assembly, repair, and manufacture of small batches make through-hole zener diodes more attractive to industrial customers.

The 2025 forecast is expected to show the strengthening of the trend toward the miniaturization of consumer, communication, and automotive devices, coupled with the adoption of integrated protection solutions and small packages. During the next three to five years, the focus for through-hole suppliers will be applications where physical robustness and the ability to handle components with ease, such as high-power, rugged, and repairable, legacy, and educational devices, will be important.
• Volatility in The Supply Chain and Price Pressures: Variability in semiconductor manufacturing, the availability of raw materials, and logistics, as well as the unpredictable costs of energy and currency exchange, can affect pricing and timely delivery. Smaller distributors are likely to confront allocation issues as the larger OEMs focus on higher volume production of new categories of semiconductors. For 2025, the impact of shortages and volatile demand require sophisticated inventory management, and most electronics manufacturers make reliable lead time a top priority when making purchase decisions. The next three to five years will bring increased focus for buyers of dual sourcing, regional inventory, and lifecycle management and increased transparency while suppliers that lack scale will experience thinning margins and customer attrition.
• Regulatory and Reliability Requirements: Clients are becoming more demanding in terms of reliability. There are regulatory requirements, environmental restrictions, and increased risks of using counterfeit components. There are also challenges associated with higher costs of testing and documentation, certification, packing, and maintaining records due to the increasing requirements for documenting the absence of hazardous substances and the increasing number of customer audits. In 2025, manufacturing of electronic devices was aligned with the RoHS requirements and the increasing supply chain transparency. In the next three to five years, more advanced automotive qualification and industrial reliability requirements will require more compliance from suppliers, potentially decreasing the competitive advantage of suppliers with low compliance costs.

Reliable demand for voltage protection and cost-effective manufacturing will support the through hole zener diode market. miniaturization and substitution of through hole devices will be restrained by technology improvements and specialized applications. However, integrated protection solutions, changes in the supply chain, increased demand for compliance and price reduction will constrain the growth of the market. Success in the market will be determined by reliable delivery, lifecycle support, product traceability, and efficient manufacturing over the next three to five years. The market is expected to experience steady application focused growth during the next three to five years, rather than rapid expansion, with most growth in rugged and repairable systems and legacy power management systems.
