In various high-current, efficient application scenarios such as switch-mode power supplies, motor drives, industrial inverters, UPS systems, and power management units, Renesas' RJK1003DPN-A0#T2, with its robust performance and low on-resistance, has been a preferred choice for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component has revealed significant pain points: extended lead times (often several months), procurement costs vulnerable to exchange rate fluctuations, and delayed technical support. These challenges severely impact production schedules and cost control for downstream enterprises. Consequently, domestic substitution has evolved from an "option" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi has introduced the VBMB1101N N-channel power MOSFET through independent R&D. This product is meticulously designed to替代 the RJK1003DPN-A0#T2, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It serves as a direct drop-in replacement without any circuit modifications, delivering a more stable, cost-effective, and locally supported solution for high-current electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the RJK1003DPN-A0#T2, the VBMB1101N achieves significant improvements in key electrical parameters, providing superior performance guarantees for high-current applications:
Firstly, the drain-source voltage remains at 100V, matching the original model, ensuring compatibility in standard voltage environments while offering a reliable foundation for various circuits.
Secondly, the continuous drain current is dramatically increased to 90A, surpassing the original model's 50A by 80%. This substantial enhancement in current-carrying capability allows seamless adaptation to higher-power designs, whether upgrading existing equipment or improving system stability at similar power levels.
Thirdly, the on-state resistance is reduced to 9mΩ (@10V gate drive),优于 the RJK1003DPN-A0#T2's 11mΩ. This lower resistance minimizes conduction losses, directly boosting overall efficiency. In high-frequency switching applications, it significantly reduces heat generation, easing thermal management demands and lowering energy costs.
Additionally, the VBMB1101N supports a ±20V gate-source voltage, providing strong gate ESD and noise immunity to prevent unintended turn-on in complex electromagnetic environments. The 2.5V gate threshold voltage balances driving convenience and switching reliability, seamlessly integrating with mainstream driver ICs without drive circuit adjustments, further simplifying substitution.
Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The RJK1003DPN-A0#T2 relies on advanced technology for low on-resistance and efficient switching. The VBMB1101N employs industry-leading Trench gate工艺, building upon the original model's strengths while optimizing device reliability. It undergoes rigorous avalanche testing and high-current screening during production, demonstrating excellent robustness against energy surges. Through optimized intrinsic capacitance design, it reduces switching losses and enhances dv/dt tolerance, ensuring stable operation in demanding conditions like high-frequency switching and fast transients. The device operates over an ultra-wide temperature range of -55°C to 150°C, adapting to harsh industrial and outdoor environments. Having passed long-term reliability tests such as high-temperature/high-humidity aging, its failure rate is well below industry averages, providing solid assurance for critical applications in motor control, power supplies, and industrial automation.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, a key concern in domestic substitution is the R&D effort and time required. The VBMB1101N addresses this through its package design. The device uses a TO-220F package, which is fully compatible with the RJK1003DPN-A0#T2's package in terms of pinout, pin spacing, dimensions, and heatsink structure. Engineers need not modify PCB layouts or thermal designs, achieving a true "plug-and-play" replacement. This high compatibility reduces substitution verification time—sample validation can typically be completed within 1-2 days—while avoiding costs associated with PCB revisions and retooling. It also preserves original product certifications and外观 designs, accelerating the supply chain cycle and enabling quick adoption of domestic alternatives.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components plagued by supply chain volatility, VBsemi leverages China's robust semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong. This ensures full-process R&D and stable mass production of the VBMB1101N. Current lead times are compressed to under 2 weeks, with emergency orders enabling 72-hour rapid delivery, mitigating risks from international logistics, tariffs, and geopolitics.
