In applications demanding robust power switching such as server/telecom power supplies, industrial motor drives, and high-intensity LED lighting, Renesas' RJK4007DPP-00#T2 has been valued for its balance of voltage rating and current handling. However, navigating today's global landscape presents challenges: extended lead times, cost volatility, and limited technical support for mature imported parts can hinder production agility and cost optimization. This reality makes sourcing a reliable, high-performance domestic alternative not just strategic but essential for maintaining competitive edge and supply chain resilience.
Addressing this critical need, VBsemi introduces the VBMB15R07S, an N-channel power MOSFET engineered through independent R&D to serve as a superior, pin-to-pin replacement for the RJK4007DPP-00#T2. It delivers key parameter enhancements, advanced technology, and full package compatibility, enabling a seamless and upgraded solution for your high-voltage designs.
Engineered for Superior Performance and Enhanced Reliability
The VBMB15R07S is designed to surpass the RJK4007DPP-00#T2 across critical specifications, providing greater design margin and robustness:
- Higher Drain-Source Voltage: Rated at 500V, a significant 100V (25%) increase over the original 400V. This provides ample safety margin against line transients and voltage spikes, enhancing system reliability in demanding industrial environments.
- Optimized Current Rating: With a continuous drain current of 7A, it robustly supports the power levels required by the target applications, offering a reliable alternative to the original 7.6A rating.
- Low On-State Resistance: Matches the excellent conduction performance with an RDS(on) of 550mΩ (@10V VGS), ensuring low conduction losses comparable to the original part for high efficiency.
- Strong Drive & Protection: Features a ±30V gate-source voltage rating, offering superior resilience against gate noise and ESD events. The 3.5V typical threshold voltage ensures reliable switching and easy integration with common driver ICs.
Advanced SJ-Multi-EPI Technology for Efficiency
While the original model utilizes a proven planar process, the VBMB15R07S leverages advanced SJ-Multi-EPI (Super Junction Multi-Epitaxial) technology. This modern approach achieves an optimal balance between low on-resistance and reduced switching losses. The result is higher overall efficiency, lower operating temperatures, and improved performance in high-frequency switching applications, contributing to better system thermal management and energy savings.
Drop-In Replacement with TO-220F Full Compatibility
The VBMB15R07S eliminates redesign risks and costs. It comes in a standard TO-220F package with pinout, dimensions, and footprint identical to the RJK4007DPP-00#T2's TO-220FP package. This allows for direct "plug-and-play" replacement on existing PCBs without any layout modifications or thermal system re-design. Engineers can validate the substitution swiftly, accelerating time-to-market for upgraded or cost-optimized products.
Guaranteed by Local Supply Chain and Expert Support
Choosing VBMB15R07S means moving beyond supply chain uncertainty. Backed by VBsemi's domestic manufacturing and vertical integration, it offers stable, predictable supply with significantly shorter lead times compared to imported alternatives. This shields your production from geopolitical, logistical, and tariff-related disruptions.
Furthermore, VBsemi provides dedicated, responsive local technical support. Our team offers comprehensive documentation, application guidance, and rapid assistance to ensure a smooth and successful replacement process, effectively solving the slow support response often associated with overseas suppliers.
From SMPS and PFC stages to motor control and lighting ballasts, the VBMB15R07S stands out as the intelligent choice for replacing the RJK4007DPP-00#T2. It combines higher voltage capability, advanced switching technology, effortless compatibility, and secure local supply into one package. Adopting the VBMB15R07S is more than a component swap—it's a strategic upgrade towards greater design robustness, supply chain control, and product competitiveness.
