In various low-voltage, high-efficiency application scenarios such as power management systems, motor drives, LED lighting, battery protection circuits, and portable electronics, Nexperia's BSP100,135, with its compact SOT223 package, low on-resistance, and reliable performance, has been a popular choice for engineers worldwide during design selection. However, in the context of global supply chain uncertainties and rising procurement challenges, this imported component has increasingly revealed several pain points: extended lead times (often 2-4 months), costs vulnerable to currency fluctuations, and delayed technical support responses. These issues significantly impact downstream companies' production efficiency and cost management. Given this industry demand, domestic substitution has evolved from an "alternative" to a "necessity," becoming a critical strategy for enterprises to ensure supply chain resilience, reduce expenses, and enhance core competitiveness.
VBsemi, leveraging years of expertise in the power semiconductor field, has introduced the VBJ1322 N-channel power MOSFET based on its independent R&D capabilities. This product is precisely tailored as a direct replacement for the BSP100,135, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a drop-in substitute without any modifications to the original circuit, providing a more efficient, cost-effective, and locally supported high-quality solution for various low-voltage electronic systems.
Comprehensive Parameter Enhancement, Superior Performance Margin, Adapting to Demanding Conditions.
Designed as a domestic alternative to the BSP100,135, the VBJ1322 achieves significant, leapfrog improvements in key electrical parameters, delivering robust performance guarantees for low-voltage applications:
First, the continuous drain current is increased to 7A, more than double the original model's 3.2A—a 119% enhancement in current-carrying capacity. This allows seamless adaptation to higher-power circuit designs, whether upgrading existing devices or improving system stability at similar power levels.
Second, the on-state resistance is drastically reduced to 19mΩ (@10V gate drive), far superior to the BSP100,135's 100mΩ (@10V, 2.2A). This represents an 81% reduction in conduction losses, directly contributing to higher overall system efficiency and reduced heat generation, thereby lowering cooling requirements and energy costs—especially in high-frequency switching applications.
Third, the drain-source voltage is maintained at 30V, matching the original model, while the gate-source voltage supports ±20V, offering enhanced gate ESD protection and noise immunity to prevent unintended turn-on in complex electromagnetic environments. The 1.7V gate threshold voltage ensures easy drive compatibility with mainstream driver ICs, requiring no additional adjustments to the drive circuit and further simplifying the substitution process.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The core strength of the BSP100,135 lies in its balance of low on-resistance and compact form factor. The VBJ1322 employs advanced Trench gate technology, building upon the original model's efficiency while optimizing device reliability across multiple dimensions. This technology enables ultra-low on-resistance and fast switching characteristics, reducing switching losses and improving overall system responsiveness. The device undergoes rigorous pre-shipment testing, including 100% electrical parameter verification and reliability screenings, ensuring excellent performance under transient conditions. With an operating temperature range of -55°C to 150°C, it withstands harsh environments such as industrial settings or outdoor applications. Additionally, it has passed long-term reliability tests, including high-temperature and humidity aging, resulting in a failure rate well below industry averages—making it ideal for critical applications like automotive electronics, industrial controls, and consumer devices where durability is paramount.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement with Zero Hassle.
For downstream enterprises, a key concern in domestic substitution is the R&D effort and time investment required. The VBJ1322 addresses this seamlessly through its package design. The device uses a standard SOT223 package, which is fully identical to the BSP100,135 in pinout, pin spacing, dimensions, and thermal pad layout. Engineers can directly replace the original component without any PCB layout changes or thermal system adjustments, achieving true "plug-and-play" convenience. This high degree of compatibility offers clear benefits: on one hand, it slashes substitution verification time, eliminating the need for circuit redesign or extensive testing—sample validation can typically be completed within 1-2 days. On the other hand, it avoids extra costs from PCB revisions or retooling, while preserving the original product's form factor and certifications. This accelerates the supply chain cycle, helping enterprises swiftly transition from imported to domestic components and capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components plagued by supply chain volatility due to international logistics, trade policies, and currency risks, VBsemi capitalizes on China's robust semiconductor ecosystem, with modern production bases and R&D centers in regions like Jiangsu and Guangdong. This ensures full-process independent R&D and stable mass production of the VBJ1322.
