In the pursuit of robust and diversified supply chains, engineers globally are seeking high-performance alternatives to established power components. For those evaluating Infineon's high-voltage CoolMOS IPP60R190P6, the superior Chinese-designed solution is VBsemi's VBM165R20S.
This is not a simple drop-in replacement. The VBM165R20S represents a strategic technological upgrade, delivering enhanced electrical performance while providing the stability and competitive advantages of a modern, diversified supply source.
Beyond Replacement: A Technical Performance Leap
While the IPP60R190P6 is a proven CoolMOS P6 series device with its 600V, 20.2A rating and super-junction technology, the VBM165R20S builds upon this foundation for superior efficiency. Featuring a higher 650V drain-source voltage in the same industry-standard TO-220 package, it delivers critical advancements:
Lower Conduction Losses: The key improvement is a significantly reduced on-resistance. At a 10V gate drive, the VBM165R20S achieves an RDS(on) of 160mΩ, a notable reduction compared to the IPP60R190P6’s 190mΩ. This translates directly into lower conduction losses, higher system efficiency, and reduced thermal stress.
Higher Voltage Ruggedness: With a 650V Vdss rating, it offers greater margin and reliability in high-voltage applications, enhancing robustness against voltage spikes.
Super-Junction Efficiency: Utilizing advanced SJ_Multi-EPI technology, it inherits the benefits of fast switching and low losses inherent to super-junction MOSFETs, ensuring high efficiency in demanding switching applications.
Where It Excels: Application Benefits
The technical edge of the VBM165R20S delivers tangible benefits in its core applications:
Switch-Mode Power Supplies (SMPS): In PFC, LLC, and flyback topologies, lower RDS(on) and superior switching performance improve overall efficiency, aiding compliance with strict energy standards.
Industrial & Consumer Power Systems: For applications like inverters, motor drives, and UPS, the combination of high voltage rating, low conduction loss, and robust current handling (20A) enables more compact, efficient, and reliable designs.
Lighting & Energy Conversion: Its high efficiency and fast switching characteristics make it ideal for high-performance LED drivers and DC-DC converters.
The Strategic Value: Performance & Supply Chain Resilience
Choosing the VBM165R20S optimizes both your design performance and supply chain strategy.
Guaranteed Performance Superiority: The specifications confirm it meets or exceeds key parameters of the IPP60R190P6, ensuring a seamless and low-risk design transition with added benefits.
Mitigate Supply Chain Risk: Sourcing from a leading Chinese manufacturer like VBsemi diversifies your supply base, providing a buffer against geopolitical uncertainties and single-source volatility.
Cost Efficiency: Competitive pricing enhances your bill of materials (BOM) cost-effectiveness, boosting product competitiveness without compromising quality.
Conclusion: The Smart Upgrade for High-Voltage Designs
VBsemi’s VBM165R20S is more than an alternative; it's a forward-looking component choice. It confidently replaces the IPP60R190P6 with proven performance, adds measurable efficiency improvements, and is backed by the strategic advantages of a resilient, diversified supply chain.
