In demanding power conversion applications such as industrial motor drives, server & telecom power supplies, and high-power LED systems, Renesas' RJK5009DPP-00#T2 power MOSFET has been a common choice for designers seeking a balance of voltage rating and current handling. However, navigating global procurement challenges—extended lead times, cost volatility, and distant support—remains a persistent hurdle. This reality accelerates the shift towards domestic alternatives, transforming them from a contingency plan into a strategic imperative for securing supply chains and optimizing cost structures.
Responding to this critical need, VBsemi introduces the VBMB155R20, a high-performance N-channel power MOSFET developed through independent R&D. This device serves as a direct, pin-to-pin replacement for the RJK5009DPP-00#T2, delivering key parameter enhancements, technological robustness, and full package compatibility. It enables a seamless transition with zero circuit modifications, offering a more reliable, cost-effective, and locally-supported solution.
Engineered for Higher Performance: Key Electrical Parameters Surpassed
The VBMB155R20 is meticulously designed to outperform the target device, providing greater design margin and efficiency:
Higher Drain-Source Voltage: Rated at 550V, a 50V (10%) increase over the original 500V (Vdss). This provides essential extra headroom for handling line transients and inductive switching spikes, enhancing system robustness in unstable grid conditions.
Lower On-State Resistance: Features an RDS(on) of just 250mΩ (at VGS=10V), significantly better than the 325mΩ of the RJK5009DPP-00#T2. This 23% reduction in conduction loss directly translates to higher efficiency, lower operating temperature, and reduced heat-sinking requirements.
Robust Current Capability: Maintains a high continuous drain current (ID) of 20A, matching the original part's current rating while operating with improved efficiency due to lower RDS(on).
Enhanced Gate Robustness: Supports a VGS of ±30V, offering superior protection against gate-source voltage spikes and noise. The optimized gate threshold voltage (Vth) of 3.5V ensures reliable switching and compatibility with standard driver ICs.
Advanced Planar Technology for Proven Reliability
While leveraging advanced Planar gate technology, the VBMB155R20 ensures high dv/dt capability and ruggedness critical for switching applications. The device undergoes rigorous 100% avalanche energy testing and high-voltage screening, guaranteeing它能承受 repetitive energy surges during turn-off. Its optimized internal capacitance reduces switching losses and improves transient response. With an operational junction temperature range of -55°C to 150°C and validated through extensive reliability testing (including 1000-hour HTGB/H3TRB), it delivers exceptional long-term stability for mission-critical industrial and communications equipment.
Seamless Drop-In Replacement: TO-220F Full Compatibility
The VBMB155R20 eliminates redesign burdens. It employs a standard TO-220F package that is mechanically and electrically identical to the RJK5009DPP-00#T2's footprint. Engineers can perform a true "drop-in" replacement without altering PCB layout, heatsink design, or assembly process. This compatibility slashes qualification time, avoids costly re-tooling, and accelerates time-to-market for your product.
Domestic Supply Chain Assurance: Stable Delivery & Local Support
VBsemi's local manufacturing and integrated supply chain ensure stable, predictable availability. Standard lead times are dramatically shorter than international alternatives, with expedited options available. This shields your production from geopolitical, logistical, and tariff-related disruptions.
