In high-power switching applications such as industrial motor drives, high-density power supplies, renewable energy inverters, and welding equipment, the IXFH28N60P3 N-channel MOSFET from Littelfuse IXYS has been a trusted component for designers, known for its robust voltage rating and switching capabilities. However, in today’s global landscape marked by supply chain volatility and extended lead times, reliance on such imported parts introduces significant risks—including unpredictable availability, cost inflation due to currency fluctuations, and delayed technical support. These challenges increasingly compel manufacturers to seek dependable, locally sourced alternatives that ensure supply chain resilience, cost stability, and responsive engineering collaboration.
Addressing this critical need, VBsemi introduces the VBP165R20S, a high-performance N-channel power MOSFET developed through independent research and advanced SJ_Multi-EPI technology. Designed as a direct, pin-to-pin replacement for the IXFH28N60P3, the VBP165R20S delivers superior electrical parameters, full package compatibility, and enhanced reliability—enabling a seamless transition with no circuit modifications required.
Superior Parameters for Demanding Applications
The VBP165R20S outperforms the IXFH28N60P3 across key specifications, providing greater design margin and efficiency:
- Higher Drain-Source Voltage: Rated at 650V, compared to 600V—offering an 8.3% increase that enhances overvoltage protection in noisy industrial environments and unstable grid conditions.
- Significantly Lower On-Resistance: Just 160mΩ at 10V VGS, substantially reducing conduction losses versus the original part. This leads to improved system efficiency, lower heat generation, and reduced cooling requirements.
- Higher Continuous Current: Supports up to 20A, enabling robust performance in higher-power circuits and ensuring reliable operation under heavy loads.
- Wide Gate-Source Voltage Range: ±30V VGS rating provides strong noise immunity and ESD protection, preventing accidental turn-on in electrically noisy environments.
- Optimized Threshold Voltage: With a Vth of 3.5V, the device ensures easy drive compatibility with standard gate drivers, simplifying design integration.
Advanced SJ_Multi-EPI Technology for Enhanced Reliability
While the IXFH28N60P3 relies on proven high-voltage MOSFET technology, the VBP165R20S incorporates VBsemi’s advanced SJ_Multi-EPI (Super Junction Multi-Epitaxial) platform. This technology achieves an optimal balance between low on-resistance and fast switching performance, while also improving avalanche energy tolerance and dv/dt capability. Each device undergoes 100% avalanche energy testing and high-voltage screening, ensuring consistent reliability under surge conditions. The wide operating temperature range (-55°C to 150°C) and rigorous reliability validation—including extended HTOL and H3TRB testing—make it suitable for mission-critical applications in industrial, automotive, and energy systems.
Drop-In Package Compatibility for Effortless Replacement
The VBP165R20S is offered in the industry-standard TO-247 package, which is mechanically and electrically identical to the IXFH28N60P3. This full pin-to-pin and footprint compatibility allows engineers to replace the existing component without any PCB layout changes, thermal redesign, or mechanical rework. The “plug-and-play” substitution significantly reduces validation time—typically requiring only 1–2 days for sample testing—and eliminates the costs and delays associated with board re-spins or recertification.
Stable Supply and Local Technical Support
Unlike imported alternatives subject to long lead times and geopolitical uncertainties, VBsemi leverages localized manufacturing and streamlined logistics to ensure stable, responsive supply. Standard lead times for the VBP165R20S are within 2–3 weeks, with expedited options available for urgent needs. Additionally, VBsemi’s domestic technical support team provides prompt, application-oriented assistance—from substitution guidance and circuit optimization to failure analysis—ensuring a smooth transition and continuous operation.
Ideal for a Broad Range of Applications
From motor drives and high-frequency power converters to UPS systems, solar inverters, and industrial welding equipment, the VBP165R20S stands out as a high-reliability, high-performance domestic alternative to the IXFH28N60P3. With its enhanced electrical characteristics, drop-in compatibility, and supply chain security, it offers engineers a risk-free path to upgrading system performance while reducing dependency on imported components.
Choosing the VBP165R20S is more than a component substitution—it is a strategic move toward supply chain autonomy, improved product performance, and long-term competitive advantage.
