In various high-current, high-frequency application scenarios such as switch-mode power supplies, motor drives, industrial inverters, welding equipment, and UPS systems, Littelfuse IXYS's IXTQ36N30P, with its advanced technology and robust performance, has long been a key choice for engineers worldwide during design selection. However, against the backdrop of global supply chain uncertainties and trade volatilities, this imported component has gradually exposed pain points: extended lead times (often several months), procurement costs affected by currency fluctuations, and delayed technical support. These issues severely impact production schedules and cost control for downstream companies. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, and enhance competitiveness.
VBsemi, with years of expertise in power semiconductors, has launched the VBPB16R47S N-channel power MOSFET based on independent R&D. This product precisely对标es the IXTQ36N30P, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without circuit modifications, providing a more stable, cost-effective, and locally attuned high-quality solution for various high-current electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the IXTQ36N30P, the VBPB16R47S achieves across-the-board improvements in key electrical parameters, offering more robust performance guarantees for high-current applications:
Firstly, the drain-source voltage is increased to 600V, double the original model's 300V—a 100% improvement. This upgrade provides a substantial safety margin in environments with voltage spikes or transient overvoltage risks, effectively preventing device failure due to overvoltage breakdown.
Secondly, the continuous drain current is raised to 47A, significantly surpassing the original model's 36A—a 30.6% enhancement in current-carrying capability. This enables effortless adaptation to higher power designs, whether upgrading equipment or improving system stability at similar power levels.
Thirdly, the on-state resistance is as low as 60mΩ (@10V gate drive), superior to the IXTQ36N30P's 110mΩ. This reduces conduction losses by nearly 45%, directly improving overall efficiency. In high-frequency switching applications, it minimizes heat generation, lowering cooling system demands and energy costs.
Additionally, the VBPB16R47S supports a ±30V gate-source voltage, offering stronger gate ESD and noise immunity, preventing unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage balances driving convenience and switching reliability, seamlessly matching mainstream driver ICs without drive circuit adjustments, further lowering substitution barriers.
Enhanced with Advanced SJ_Multi-EPI Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the IXTQ36N30P lies in its low on-resistance and high switching performance. The VBPB16R47S employs industry-leading SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, building upon excellent switching characteristics while optimizing reliability. The device undergoes rigorous avalanche testing and high-voltage screening before leaving the factory, exhibiting robust single-pulse avalanche energy capability. It handles energy surges during high-current turn-off with ease, reducing the risk of avalanche breakdown damage. Through optimized capacitance design, it reduces charge/discharge losses during switching and enhances dv/dt tolerance, perfectly matching IXTQ36N30P application scenarios. Even under harsh conditions like high-frequency switching and fast transients, it maintains stable operation with direct replacement. Furthermore, the VBPB16R47S features an ultra-wide operating temperature range of -55°C to 150°C, adapting to industrial high-temperature environments and outdoor extremes. Having passed long-term reliability tests such as 1000-hour high-temperature/high-humidity (85°C/85% RH) aging, its failure rate is below industry averages, providing solid assurance for continuous operation—ideal for critical fields like industrial control, motor drives, and power supplies.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern is the R&D investment in substitution. The VBPB16R47S addresses this through package design. The device uses a TO3P package, identical to the IXTQ36N30P's package in pinout, pin spacing, dimensions, and heatsink structure. Engineers need not modify PCB layouts or thermal designs, achieving "plug-and-play" replacement. This compatibility reduces verification time—sample validation typically completes in 1-2 days—and avoids costs from PCB revisions or mold adjustments. It ensures original product dimensions remain unchanged, eliminating re-certification needs, shortening supply cycles, and helping enterprises quickly upgrade imported components.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to unstable imported supply chains, VBsemi leverages China's semiconductor industry chain, with production bases and R&D centers in Jiangsu, Guangdong, etc., enabling full-process R&D and stable mass production of the VBPB16R47S. Lead times are compressed to under 2 weeks, with emergency orders allowing 72-hour delivery. This mitigates risks from supply chain volatility, tariffs, and geopolitics, ensuring smooth production plans. As a local brand, VBsemi offers professional technical support with "one-on-one" services: providing comprehensive documentation (substitution reports, datasheets, thermal guides, application circuits) and tailored solutions based on customer scenarios. For technical issues during substitution, the team responds within 24 hours for on-site or remote resolution. This addresses slow support and high communication costs of imported components, making substitution smoother.
From industrial power supplies and motor drives to welding machines and UPS systems; from renewable energy charging equipment to high-frequency inverters, the VBPB16R47S, with its core advantages of "superior parameters, stable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the IXTQ36N30P. It has gained application in leading companies across industries, receiving high market recognition. Choosing the VBPB16R47S is not just a component replacement; it is a crucial step for enterprises in upgrading supply chain security, optimizing costs, and enhancing competitiveness—requiring no R&D modification risks while enjoying better performance, stable supply, and convenient support.
