In various medium-voltage, low-power application scenarios such as power management, motor drives, battery protection circuits, and industrial automation, Infineon's BSP317P H6327, with its P-channel enhancement mode, logic level design, dv/dt rating, and compliance with AEC-Q101 and halogen-free standards, has been a trusted choice for engineers globally. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces significant challenges: extended lead times (often several months), procurement costs vulnerable to currency fluctuations, and delayed technical support. These issues hinder production schedules and cost optimization for downstream companies. Given this industry demand, domestic substitution has evolved from an "option" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBJ2251K P-channel power MOSFET based on independent R&D. This product directly对标es the BSP317P H6327, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for various medium-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the BSP317P H6327, the VBJ2251K achieves significant improvements in key electrical parameters, providing robust performance for medium-voltage applications:
First, the drain-source voltage is maintained at 250V, matching the original model's rating, but with enhanced reliability through advanced manufacturing. This ensures stable operation in environments with voltage fluctuations, such as consumer electronics and industrial controls.
Second, the continuous drain current is大幅increased to 2.1A, a substantial leap from the original model's 430mA—representing a nearly 5x enhancement in current-carrying capability. This allows effortless handling of higher power loads, enabling upgrades to more demanding circuits or improved efficiency in existing designs.
Third, the on-state resistance is optimized to 1200mΩ (@10V gate drive), comparable to the BSP317P H6327's performance but with better consistency. This reduces conduction losses, improving overall system efficiency and minimizing heat generation, which is critical for compact designs in applications like battery management and LED drivers.
Additionally, the VBJ2251K supports a ±20V gate-source voltage, offering stronger gate ESD and noise immunity, preventing unintended turn-on in noisy environments. The -2V gate threshold voltage (logic level compatible) ensures easy driving with mainstream ICs, requiring no adjustments to drive circuits, thus lowering substitution barriers.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The BSP317P H6327 relies on its P-channel enhancement mode and dv/dt tolerance for reliability. The VBJ2251K employs advanced Trench technology, building upon the original model's strengths while optimizing device performance. Through rigorous testing, including 100% screening and avalanche energy validation, it exhibits excellent robustness against voltage spikes and switching stresses. The optimized intrinsic capacitance design reduces switching losses and improves dv/dt tolerance, ensuring stable operation in high-frequency scenarios like power supplies and motor drives. Furthermore, the VBJ2251K features a wide operating temperature range and has passed long-term reliability tests, such as high-temperature/high-humidity aging, with a failure rate below industry averages. This makes it ideal for critical applications requiring durability, such as automotive electronics, medical devices, and industrial systems.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, substitution costs and efforts are key concerns. The VBJ2251K addresses this through its package design. The device uses a SOT223 package, identical to the BSP317P H6327 in pinout, spacing, dimensions, and thermal structure. Engineers can replace it directly without PCB layout changes or thermal redesign, achieving "plug-and-play" convenience. This high compatibility reduces verification time—sample testing can be completed in 1-2 days—and avoids additional costs from PCB revisions or retooling. It also preserves original product certifications and外观designs, accelerating the substitution process and helping enterprises quickly upgrade imported components.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Compared to imported components affected by logistics, trade policies, and exchange rates, VBsemi leverages China's robust semiconductor产业链, with modern production bases in Jiangsu and Guangdong. This enables full-process R&D and stable mass production of the VBJ2251K. Current lead times are compressed to within 2 weeks, with emergency orders offering 72-hour delivery, mitigating risks from global supply chain volatility.
