In today's demanding power electronics landscape, engineers seek components that deliver both peak performance and supply chain security. If you are considering the established high-voltage MOSFET, Infineon's IPW65R150CFD, for your next design, evaluate the advanced Chinese-designed alternative: VBsemi's VBP165R20S.
This is not just a simple replacement. The VBP165R20S represents a strategic, performance-optimized choice, offering robust electrical characteristics alongside the stability and competitive advantages of a modern, diversified supply chain.
Beyond Direct Replacement: Engineered for Robust Performance
The IPW65R150CFD, part of the CoolMOS CFD2 series, is a proven solution featuring a fast and rugged body diode, built on superjunction (SJ) technology for high efficiency. The VBP165R20S builds upon this solid foundation with key specifications tailored for reliability and design flexibility.
Core Electrical Comparison & Advantages:
Voltage & Technology Parity: Both devices are 650V N-channel SJ MOSFETs in the TO-247 package, ensuring compatibility in high-voltage applications like PFC, LLC converters, and motor drives.
Optimized Current Handling: The VBP165R20S offers a robust 20A continuous drain current, providing a reliable current rating for demanding circuits.
Balanced Conduction Performance: With an on-resistance (RDS(on)) of 160mΩ at 10V gate drive, the VBP165R20S presents a well-balanced specification. This ensures low conduction losses for high efficiency while contributing to excellent switching performance and diode ruggedness—a critical factor in hard- and resonant-switching topologies.
Enhanced Design Margin: The device features a ±30V gate-source voltage rating, offering a wider safe operating area and greater noise immunity in challenging switching environments compared to many standard alternatives.
Where It Excels: Application Benefits
The technical profile of the VBP165R20S translates into tangible benefits for its target applications:
Switch-Mode Power Supplies (SMPS): In PFC stages, LLC resonant converters, and high-voltage DC-DC applications, its 650V rating and SJ technology ensure low switching and conduction losses, aiding compliance with efficiency standards like 80 PLUS.
Industrial & Renewable Energy Systems: For solar inverters, UPS systems, and industrial motor drives, the combination of high voltage, ruggedness, and efficient switching supports reliable, high-power-density designs.
Applications Demanding Diode Ruggedness: The inherent advantages of the SJ Multi-EPI process contribute to a fast and robust intrinsic body diode, making it a reliable choice for circuits with hard commutation or freewheeling paths.
The Strategic Value: Reliability & Supply Chain Resilience
Choosing the VBP165R20S is a decision that strengthens both your design and your supply chain strategy.
Guaranteed Performance Compatibility: The VBP165R20S is engineered to meet the critical requirements for replacing the IPW65R150CFD in high-voltage applications, ensuring a smooth and low-risk design transition.
Mitigate Supply Chain Risk: Sourcing from a leading Chinese manufacturer like VBsemi diversifies your supply base. This provides a crucial buffer against geopolitical uncertainties, allocation shortages, or price volatility from single-source suppliers.
Cost-Effective Performance: The competitive value proposition of domestic Chinese components can reduce your overall system cost, enhancing your product's market competitiveness without compromising on quality or reliability.
