In various low-voltage, high-efficiency application scenarios such as portable electronics, power management systems, motor drives, and battery-powered devices, ROHM's RTL035N03TR, with its low on-resistance and compact package, has been a popular choice for engineers worldwide. However, in the post-pandemic era with global supply chain disruptions and trade uncertainties, this imported component faces issues like unstable lead times, cost fluctuations, and delayed technical support, which hinder production schedules and cost control. Therefore, domestic substitution has become a necessity for ensuring supply chain security and enhancing competitiveness.
VBsemi, with its expertise in power semiconductors, introduces the VBK7322 N-channel MOSFET as a direct alternative to the RTL035N03TR. This product offers parameter upgrades, technological parity, and full package compatibility, enabling a drop-in replacement without circuit modifications, providing a more stable and cost-effective solution.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the RTL035N03TR, the VBK7322 achieves significant improvements in key electrical parameters:
Firstly, the continuous drain current is increased to 4.5A, compared to the original 3.5A—a 28.6% enhancement, allowing for higher current applications and improved stability.
Secondly, the on-state resistance is as low as 23mΩ at 10V gate drive, which is significantly lower than the original's 56mΩ at 4.5V. This reduction minimizes conduction losses, improving overall efficiency and reducing heat generation in high-frequency switching applications.
Additionally, the VBK7322 supports a ±20V gate-source voltage, offering robust gate protection and noise immunity. The 1.7V gate threshold voltage ensures easy drive compatibility with mainstream driver ICs, facilitating seamless integration.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The VBK7322 utilizes advanced Trench technology, which optimizes switching characteristics and device reliability. It undergoes rigorous testing, including 100% avalanche and high-voltage screening, ensuring excellent performance under transient conditions. The device features a wide operating temperature range from -55°C to 150°C, suitable for harsh environments. Long-term reliability tests, such as high-temperature/high-humidity aging, confirm its durability, making it ideal for critical applications like consumer electronics, industrial controls, and automotive systems.
Fully Compatible Package, Enabling Seamless Replacement.
The VBK7322 comes in an SC70-6 package, identical to the RTL035N03TR in pinout, dimensions, and thermal characteristics. Engineers can directly replace the original component without modifying PCB layouts or thermal designs, achieving "plug-and-play" substitution. This compatibility reduces verification time to 1-2 days, avoids redesign costs, and accelerates time-to-market.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Leveraging China's robust semiconductor industry chain, VBsemi ensures stable mass production of the VBK7322 with lead times within 2 weeks and expedited delivery options. This mitigates risks from international supply chain volatility. Moreover, VBsemi provides dedicated technical support with comprehensive documentation, substitution reports, and application guidance. Technical issues are addressed within 24 hours, eliminating communication barriers associated with imported components.
From portable devices and power tools to battery management systems and LED drivers, the VBK7322, with its superior parameters, stable performance, package compatibility, controlled supply, and responsive service, has become the preferred alternative to the RTL035N03TR. It has been adopted by leading companies across industries, gaining market recognition. Choosing the VBK7322 is not just a component replacement but a strategic move to secure supply chains, reduce costs, and enhance product competitiveness—all without R&D risks, while enjoying better performance, reliable supply, and local support.
