In high-current application scenarios such as switch-mode and resonant-mode power supplies, as well as DC-DC converters, Littelfuse IXYS's IXFH150N25X3, with its low on-resistance (RDS(ON)), low gate charge (QG), avalanche rating, low package inductance, and high power density, has been a preferred choice for engineers globally. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces challenges like extended lead times (often several months), cost volatility due to exchange rates, and delayed technical support. These issues hinder production schedules and cost control for downstream enterprises. Consequently, domestic substitution has evolved from an "option" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBGP1252N N-channel power MOSFET through independent R&D. This product is designed as a direct alternative to the IXFH150N25X3, offering core advantages of technological parity, full package compatibility, and reliable performance. It enables seamless replacement without circuit modifications, providing a stable, cost-effective, and locally supported solution for high-current electronic systems.
Optimized Performance with Advanced SGT Technology, Ensuring Reliability and Efficiency.
Tailored as a domestic alternative to the IXFH150N25X3, the VBGP1252N delivers balanced performance enhancements tailored for demanding applications. It maintains a drain-source voltage of 250V, matching the original model, ensuring compatibility in standard voltage environments. The continuous drain current is rated at 100A, supported by a robust design that prioritizes stability and thermal management. Although the on-state resistance is 16mΩ (@10V gate drive), compared to the IXFH150N25X3's 9mΩ, the VBGP1252N incorporates Shielded Gate Trench (SGT) technology, which optimizes switching characteristics, reduces gate charge, and improves overall efficiency in high-frequency operations. This technology also enhances dv/dt tolerance and avalanche robustness, reducing the risk of device failure under transient conditions. The gate-source voltage rating of ±20V and a gate threshold voltage of 3.5V ensure strong noise immunity and easy integration with mainstream driver ICs, minimizing drive circuit adjustments. Additionally, the device operates over a wide temperature range and undergoes rigorous reliability testing, including high-temperature and humidity aging, to ensure long-term stability in harsh environments such as industrial power systems and automotive applications.
Full Package Compatibility, Enabling "Drop-In" Replacement with Zero Design Overhead.
A key concern in domestic substitution is the cost and effort of redesign. The VBGP1252N addresses this through its TO-247 package, which is fully compatible with the IXFH150N25X3 in pinout, dimensions, and heatsink mounting. Engineers can directly replace the component on existing PCB layouts without modifying thermal designs or undergoing recertification. This "plug-and-play" approach slashes substitution time—sample validation can be completed within days—and avoids additional expenses from PCB revisions or mold changes. By preserving original structural and electrical interfaces, it streamlines the supply chain and accelerates time-to-market for enterprises seeking import substitution.
Localized Strength Guarantee, Dual Assurance for Supply Chain and Technical Support.
Unlike imported components susceptible to logistics delays, trade policies, and currency fluctuations, VBsemi leverages domestic semiconductor infrastructure with production bases in Jiangsu and Guangdong. This enables stable mass production of the VBGP1252N, with lead times compressed to under two weeks and expedited options for urgent orders. Such control mitigates risks from global supply chain volatility and geopolitical factors, ensuring uninterrupted production plans. As a local brand, VBsemi provides dedicated technical support, including comprehensive documentation (e.g., substitution reports, datasheets, application guides) and personalized circuit optimization advice. The technical team offers rapid response within 24 hours for any substitution issues, resolving pain points like slow support and high communication costs associated with imported components.
From switch-mode and resonant power supplies to DC-DC converters, motor drives, and renewable energy systems, the VBGP1252N stands out as a premier domestic alternative to the IXFH150N25X3, with strengths in "package compatibility, stable performance, secure supply, and responsive service." It has already been adopted by leading enterprises across industries, gaining strong market recognition. Choosing the VBGP1252N is not merely a component swap—it is a strategic move to bolster supply chain resilience, optimize costs, and elevate product competitiveness, all without R&D risks while benefiting from localized advantages.
