In various high-frequency switching application scenarios such as DC-DC converters, power management systems, motor drives, and automotive electronics, Infineon's BSZ160N10NS3G, with its optimized technology for DC-DC conversion, excellent gate charge×R_DS(on) figure of merit, 100% avalanche testing, and halogen-free compliance, has long been a key choice for engineers worldwide during design selection. However, against the backdrop of global supply chain uncertainties and trade volatility, this imported component has gradually exposed pain points: extended lead times, procurement costs affected by currency fluctuations, and delayed technical support. These issues hinder production schedules and cost control for downstream companies. Given this industry demand, domestic substitution has evolved from an "option" to a "necessity," becoming a critical path for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, with deep expertise in power semiconductors, launches the VBQF1101N N-channel power MOSFET based on independent R&D. This product precisely对标es the BSZ160N10NS3G, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a direct replacement without circuit modifications, providing a more stable, cost-effective, and locally attuned high-quality solution for high-frequency electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the BSZ160N10NS3G, the VBQF1101N achieves leapfrog improvements in key electrical parameters, delivering robust performance for high-frequency applications:
Firstly, the drain-source voltage remains at 100V, matching the original model, while the continuous drain current is dramatically increased to 50A, far surpassing the original model's 8A—a 525% enhancement in current-carrying capability. This enables effortless handling of higher power loads, whether upgrading existing designs or improving system stability.
Secondly, the on-state resistance is reduced to 10mΩ (@10V gate drive), significantly lower than the BSZ160N10NS3G's 16mΩ (@10V, 20A)—a 37.5% improvement. This minimizes conduction losses, boosting overall efficiency and reducing heat generation in high-frequency switching, thereby alleviating cooling system demands.
Thirdly, the gate threshold voltage is optimized to 2.5V, ensuring smooth driving compatibility with mainstream driver ICs. The ±20V gate-source voltage rating offers strong ESD and noise immunity, preventing unintended turn-on in noisy environments. These features ensure reliable switching without drive circuit adjustments.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The core advantage of the BSZ160N10NS3G lies in its optimized design for DC-DC conversion and high figure of merit. The VBQF1101N employs advanced Trench technology, building upon the original model's switching performance while enhancing reliability. The device undergoes rigorous avalanche testing and high-voltage screening, ensuring excellent energy handling during transient events. Through optimized intrinsic capacitance design, it reduces switching losses and improves dv/dt tolerance, matching the BSZ160N10NS3G's application scenarios seamlessly. Even under high-frequency switching and fast transients, it maintains stable operation. Additionally, the VBQF1101N features a wide operating temperature range and has passed long-term reliability tests, with a failure rate below industry averages, making it suitable for critical fields like automotive, industrial control, and telecommunications.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, a core concern is the R&D effort in replacement. The VBQF1101N addresses this through its package design. The device uses a DFN8(3x3) package, which is fully compatible with the BSZ160N10NS3G in pinout, dimensions, and thermal characteristics. Engineers need not modify PCB layouts or thermal designs, achieving "plug-and-play" convenience. This compatibility slashes verification time—sample validation can be done within 1-2 days—and avoids costs from PCB revisions or retooling. It ensures unchanged product structures, eliminating re-certification needs, thus accelerating supply chain cycles and helping enterprises swiftly upgrade imported components.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Compared to imported components with unstable supply chains, VBsemi leverages China's robust semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong, enabling full-process R&D and stable mass production of the VBQF1101N. Lead times are compressed to within 2 weeks, with emergency orders supporting 72-hour delivery, mitigating risks from international logistics, tariffs, or geopolitics.
