In demanding high-voltage, high-current applications such as industrial motor drives, power supply units, inverters, and energy management systems, ROHM's R6015ANX N-channel MOSFET has been a reliable component valued for its balance of voltage rating and current handling. However, in the current global landscape marked by supply chain uncertainties and logistical challenges, dependence on imported parts like the R6015ANX introduces risks—extended lead times, cost volatility, and potential delays in technical support. This environment makes domestic substitution not just a strategic option but a critical step for ensuring production stability, cost efficiency, and supply chain resilience.
Addressing this market need, VBsemi introduces the VBMB165R20S, a high-performance N-channel power MOSFET developed through independent research and advanced SJ_Multi-EPI technology. Designed as a direct and superior alternative to the R6015ANX, the VBMB165R20S delivers enhanced electrical parameters, full package compatibility, and the reliability required for next-generation high-power designs, offering a seamless, high-value replacement solution.
Performance Surpassing Specifications, Built for Higher Demands
As a targeted upgrade to the R6015ANX, the VBMB165R20S achieves significant advancements across all key parameters, providing greater margin and robustness in operation:
Higher Voltage Rating: The drain-source voltage is elevated to 650V, exceeding the original 600V. This provides an increased safety buffer against line surges and transient overvoltages commonly encountered in industrial settings, enhancing system-level reliability.
Superior Current Capability: With a continuous drain current rating of 20A, the VBMB165R20S offers a substantial 33% increase over the R6015ANX's 15A. This allows it to handle higher power levels effortlessly, enabling design upgrades or providing additional headroom for improved thermal performance in existing applications.
Drastically Reduced Conduction Losses: The standout feature is an on-state resistance (RDS(on)) of just 160mΩ (measured at VGS=10V), which is nearly 50% lower than the 300mΩ of the R6015ANX (measured at 7.5A). This dramatic reduction minimizes power loss during conduction, directly boosting system efficiency, reducing heat generation, and simplifying thermal management.
Robust Gate Drive: Supporting a gate-source voltage range of ±30V, the device ensures excellent immunity against gate noise and ESD events. The 3.5V typical threshold voltage ensures compatibility with a wide array of standard driver ICs, facilitating easy integration without circuit modifications.
Advanced SJ_Multi-EPI Technology for Uncompromised Reliability
The VBMB165R20S leverages VBsemi's proprietary SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology. This advanced process delivers the low RDS(on) and excellent switching performance required for high-frequency, high-efficiency applications. The device is subjected to rigorous 100% avalanche energy testing and high-voltage screening during production, ensuring it can withstand harsh energy surges during switching events. Its optimized internal capacitance results in lower switching losses and high dv/dt capability, matching or exceeding the performance benchmarks of the original part. With an operational temperature range of -55°C to 150°C and validation through extended reliability tests (including 1000-hour HTOL/H3TRB), the VBMB165R20S is built for long-term durability in challenging environments, from industrial automation to renewable energy systems.
Seamless Drop-In Replacement with TO-220F Package
The VBMB165R20S is designed for a frictionless substitution process. It utilizes the industry-standard TO-220F package, which is fully compatible in footprint, pinout, and mechanical dimensions with the package of the R6015ANX. Engineers can replace the component directly on the existing PCB layout without any redesign of the circuit or heatsink attachment. This "plug-and-play" compatibility eliminates the need for costly and time-consuming re-qualification, allowing companies to transition to a domestic alternative rapidly—often within days for sample verification—while avoiding additional costs for mold changes or recertification.
Guaranteed Supply and Localized Technical Support
VBsemi's domestic manufacturing infrastructure ensures a stable and responsive supply chain for the VBMB165R20S, starkly contrasting the uncertainties of international procurement. Standard lead times are consistently within 2-4 weeks, with expedited options available for urgent needs.
