IntroductionIn the decision-making process of component selection and procurement, many teams often prioritize "unit price" as the primary consideration. However, an unassuming MOSFET is associated with far more than just procurement costs—it is closely linked to the overall product's reliability, service life, and brand reputation. Neglecting hidden quality risks may ultimately result in costs that far exceed expectations.

I. Potential Costs Behind Low PricesWhen a MOSFET is quoted significantly below market levels, procurement teams and decision-makers should investigate the source of its cost optimization. Does it stem from efficiency improvements through technological innovation? Or is it achieved by cutting quality control processes, lowering material standards, or reducing testing coverage? The latter often implies substantial hidden risks:

Increased early failure rates: Especially in high-voltage, high-current applications such as motor drives and power conversion, devices face frequent switching impacts and thermal stress. MOSFETs with internal process defects or inconsistent parameters are prone to failures like gate oxide breakdown and channel degradation, leading to early equipment malfunctions and significantly higher after-sales maintenance costs.

Field failures and brand trust crises: Compared to controllable testing during production, failures in real-world use after product launch cause far greater losses. They not only incur direct costs from returns, logistics, and handling but may also trigger long-term user doubts about brand quality, damaging market reputation built over years.

System compatibility and debugging costs: MOSFETs with large parameter fluctuations between batches can lead to inconsistent product performance. Engineers may need to spend extensive additional time on system debugging and re-verification, or even modify designs to accommodate component deficiencies—undoubtedly increasing hidden R&D costs.

II. How to Identify and Mitigate These Risks?Sound procurement decisions should be based on a Total Cost of Ownership (TCO) perspective rather than focusing solely on unit price. This requires evaluating suppliers from the following aspects:

Technological and design expertise: Pay attention to the supplier’s core process technologies. For example, MOSFETs using Shielded Gate Trench (SGT) technology better balance conduction loss and switching performance while offering stronger impact resistance and reliability, enhancing robustness from the design stage.

Quality management systems: Assess whether the supplier has established rigorous quality control systems covering the entire lifecycle from design, manufacturing to packaging and testing. This includes the adoption of high-standard electrostatic discharge (ESD) protection, strict dynamic parameter testing, and 100% reliability screening (e.g., HTRB testing) to ensure high consistency and durability of delivered products.

Testing standards and data support: Reliable suppliers should provide detailed product test reports and data, such as Failure In Time (FIT) metrics and Avalanche Energy (Eas) test data—critical indicators for evaluating long-term device reliability.

Supply chain transparency and support capabilities: Evaluate the supplier’s supply chain stability and technical support capacity. Can they ensure stable supply? Do they offer timely technical support and selection advice during product development? These factors are crucial for reducing project risks when it matters most.
