In various high-current, high-efficiency application scenarios such as synchronous rectification, DC-DC converters, motor drives, and power tools, Infineon's BSZ018N04LS6, with its optimization for synchronous rectification, extremely low on-resistance, and excellent thermal performance, has been a preferred choice for engineers worldwide. However, against the backdrop of intensified global supply chain disruptions and frequent international trade frictions in the post-pandemic era, this imported component has gradually exposed numerous pain points: unstable lead times, procurement costs susceptible to exchange rate fluctuations, and lagging technical support responses. These issues severely constrain downstream companies' production schedules and cost control. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, enhance efficiency, and improve core competitiveness.
VBsemi, with years of deep cultivation in the power semiconductor field, has launched the VBGQF1402 N-channel power MOSFET based on its independent SGT (Shielded Gate Transistor) technology. This product precisely targets the BSZ018N04LS6, offering core advantages of parameter matching, technological upgrade, and package optimization. It can serve as a direct replacement in many applications, providing a more stable, cost-effective, and locally attuned high-quality solution for various high-current electronic systems.
Comprehensive Parameter Matching, Enhanced Performance, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the BSZ018N04LS6, the VBGQF1402 achieves close alignment in key electrical parameters with additional benefits: The drain-source voltage is 40V, identical to the original model, ensuring compatibility in low-voltage designs. The continuous drain current of 100A, while slightly lower, remains ample for most high-current circuits, and the on-state resistance is as low as 2.2mΩ (@10V gate drive), comparable to the original's 1.8mΩ, minimizing conduction losses and boosting efficiency. The gate-source voltage of ±20V provides robust gate protection and noise immunity, and the 3V gate threshold voltage balances drive convenience and switching reliability, seamlessly matching mainstream driver ICs without circuit modifications.
Enhanced with Advanced SGT Technology, Reliability and Stability Upgraded.
The BSZ018N04LS6 excels with its low on-resistance and synchronization rectification optimization. The VBGQF1402 employs SGT technology, which reduces gate charge, enhances switching speed, and improves dv/dt tolerance. The device undergoes 100% avalanche testing and features a wide operating temperature range up to 175°C, ensuring reliable operation under high-current switching conditions. Through optimized intrinsic capacitance design, it lowers switching losses and elevates thermal performance, reducing failure risks in demanding environments like industrial motor drives and power supplies. Long-term reliability verification and high-temperature/high-humidity aging tests further solidify its durability for critical applications.
Compact Package Design, Enabling Space-Efficient and Swift Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment in redesign. The VBGQF1402 addresses this with its DFN8(3x3) package, offering a compact footprint ideal for space-constrained layouts. While not pin-to-pin identical to all packages, its modern design simplifies thermal management and board integration. Engineers can adapt existing designs with minimal adjustments, avoiding major PCB revisions and mold changes. This reduces substitution verification time to typically 1-2 days, accelerates supply chain cycles, and helps enterprises quickly achieve import component replacement without significant overhead.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to the unstable supply chain of imported components affected by international logistics and trade policies, VBsemi leverages China's robust semiconductor industry chain, with production bases and R&D centers enabling full-process control. The VBGQF1402 has a standard lead time compressed to within 2 weeks, with emergency orders supporting 72-hour rapid delivery, mitigating risks from volatility, tariffs, and geopolitics. As a local brand, VBsemi provides professional technical support: comprehensive documentation including substitution verification reports, datasheets, and application guides, plus 24-hour response for technical issues. This彻底 addresses slow support and high communication costs, ensuring a smooth and worry-free substitution process.
From synchronous rectification in switch-mode power supplies and DC-DC converters to motor drives in industrial equipment and power tools; from battery management systems to new energy applications, the VBGQF1402, with its core advantages of "parameter matching, advanced SGT technology, compact package, controllable supply, and attentive service," has become a preferred solution for domestic substitution of the BSZ018N04LS6. It has already achieved application in several leading companies, receiving high market recognition. Choosing the VBGQF1402 is not merely a simple component replacement; it is a strategic step for enterprises in upgrading supply chain security, optimizing production costs, and enhancing product competitiveness—offering reliable performance, stable supply, and convenient support without assuming major R&D modification risks.
