In various low-voltage, high-efficiency application scenarios such as portable devices, battery management systems, power switches, load switches, and automotive electronics, Infineon's BSD235N H6327, with its dual N-channel enhancement-mode design, super logic level rating (2.5V), avalanche rating, and AEC Q101 certification, has long been a key choice for engineers worldwide during design selection. 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 VBK3215N dual N-channel power MOSFET based on its independent R&D capabilities. This product precisely对标es the BSD235N H6327, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without any modifications to the original circuit, providing a more stable, cost-effective, and locally attuned high-quality solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the BSD235N H6327, the VBK3215N achieves across-the-board, leapfrog improvements in key electrical parameters, offering more robust performance guarantees for low-voltage applications:
Firstly, the continuous drain current is increased to 2.6A, significantly surpassing the original model's 950mA—a 174% enhancement in current-carrying capability. This enables effortless adaptation to higher current-level circuit designs, whether upgrading existing equipment to higher-power versions or improving system operational stability at the same power level.
Secondly, the on-state resistance is as low as 110mΩ (@4.5V gate drive), superior to the BSD235N H6327's 350mΩ (@4.5V, 0.95A). This represents a 68.6% reduction in conduction resistance, further reducing conduction losses, directly contributing to improved overall efficiency and heat generation reduction, especially in high-frequency switching applications.
Additionally, the VBK3215N supports a ±12V gate-source voltage, offering stronger gate ESD and noise immunity. The gate threshold voltage range of 0.5V to 1.5V ensures compatibility with super logic level driving (rated 2.5V), perfectly matching low-voltage driver ICs on the market without requiring additional adjustments to the drive circuit, further lowering the barrier to substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the BSD235N H6327 lies in its super logic level rating, avalanche capability, and AEC Q101 certification. The VBK3215N employs industry-leading Trench technology, building upon the excellent switching characteristics of the original model while optimizing device reliability across multiple dimensions. The device features avalanche rating and undergoes rigorous testing before leaving the factory, exhibiting excellent robustness against voltage surges. Through optimized structural design, it not only reduces switching losses but also enhances overall durability, perfectly matching the application scenarios of the BSD235N H6327. Even under harsh conditions like fast transients and high-frequency operation, it maintains stable performance and can be directly replaced without modifying the circuit topology. Furthermore, the VBK3215N is designed to meet automotive-grade standards, with 100% lead-free, RoHS compliance, and halogen-free (according to IEC61249-2-21) materials, ensuring environmental friendliness and safety. Having passed long-term reliability verification, its failure rate is far below the industry average, providing solid assurance for critical fields such as automotive electronics, portable devices, and industrial controls.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment and time costs involved in the replacement process. The VBK3215N fundamentally addresses this pain point through its package design. The device uses an SC70-6 package, which is completely identical to the BSD235N H6327's package in terms of pinout, pin spacing, and dimensions. Engineers need not make any modifications to the original PCB layout or adjust the thermal system design, achieving a "plug-and-play" convenient replacement. The advantages brought by this high degree of compatibility are evident: on one hand, it significantly reduces the time cost of substitution verification, eliminating the need for R&D teams to invest in circuit redesign, simulation, and testing—sample validation can typically be completed within 1-2 days. On the other hand, it avoids increased production costs from PCB revisions and mold adjustments while ensuring the original product's structural dimensions remain unchanged, eliminating the need for re-certification and外观 design. This effectively shortens the supply chain cycle, helping enterprises quickly achieve the substitution and upgrade of imported components and seize market opportunities.
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 multiple factors like international logistics, trade policies, and exchange rate fluctuations, VBsemi leverages China's well-established semiconductor industry chain layout, with modern production bases and R&D centers in Jiangsu, Guangdong, and other locations. This enables full-process independent R&D and stable mass production of the VBK3215N. Currently, the standard lead time for this model is compressed to within 2 weeks, with emergency orders enabling 72-hour rapid delivery. This effectively mitigates various risks such as international supply chain volatility, tariff barriers, and geopolitics, providing solid assurance for the smooth progress of enterprise production plans. Simultaneously, as a local brand, VBsemi boasts a professional technical support team offering "one-on-one" customized services: not only providing comprehensive technical documentation, including detailed substitution verification reports, device datasheets, thermal design guides, and application circuit references, but also offering targeted selection advice and circuit optimization solutions based on specific customer application scenarios. For any technical issues arising during the substitution process, the technical team can provide rapid response within 24 hours, assisting with on-site or remote resolution. This彻底addresses the pain points of slow technical support response and high communication costs associated with imported components, making the substitution process smoother and more worry-free.
From portable devices and battery management systems to power switches and load switches; from automotive electronics and industrial controls to consumer electronics and IoT applications, the VBK3215N, with its core advantages of "superior parameters, more stable performance, package compatibility, controllable supply, and attentive service," has become the preferred solution for domestic substitution of the Infineon BSD235N H6327. It has already achieved application in several leading companies across multiple industries, receiving high market recognition. Choosing the VBK3215N is not merely a simple component replacement; it is a crucial step for enterprises in upgrading supply chain security, optimizing production costs, and enhancing product competitiveness—requiring no assumption of R&D modification risks while enjoying superior performance, more stable supply, and more convenient technical support.
