MARKET RESTRAINTS

Material Limitations and Thermal Constraints to Hinder Market Expansion

While Small Signal Schottky Diodes offer significant advantages, their performance limitations at higher voltage ranges create adoption barriers in certain applications. The conventional silicon-based Schottky diodes typically exhibit increased leakage currents when operating above 100V, restricting their use in medium-voltage power applications. This limitation has prompted some design engineers to opt for alternative solutions like fast recovery diodes in systems requiring higher breakdown voltages, potentially limiting market growth in specific segments.

The thermal management challenges associated with high-density integration also pose significant restraints. As electronic devices continue to shrink in size while increasing in functionality, the heat dissipation requirements become more stringent. Schottky diodes, while efficient, still generate junction temperatures that can affect performance reliability in tightly packed PCB designs. These thermal considerations often necessitate additional cooling solutions, increasing overall system costs and complexity.

MARKET CHALLENGES

Supply Chain Vulnerabilities and Geopolitical Factors to Test Market Resilience
