In various high-voltage, high-frequency application scenarios such as switch-mode power supplies, industrial inverters, LED lighting drivers, welding machines, and UPS systems, STMicroelectronics' STFU11N65M2, with its proprietary MDmesh M2 technology, low on-resistance, and excellent switching performance, has been a preferred choice for engineers worldwide. However, in the post-pandemic era with intensified global supply chain disruptions and frequent international trade frictions, this imported component has exposed pain points: unstable lead times, procurement costs affected by exchange rate fluctuations, and lagging technical support. These issues severely constrain 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 deep cultivation in the power semiconductor field, launches the VBMB165R07S N-channel power MOSFET based on its independent R&D capabilities. This product precisely对标es the STFU11N65M2, offering core advantages of parameter parity, technological advancement, and full package compatibility. It can serve as a direct replacement without modifications to the original circuit, providing a more stable, cost-effective, and locally attuned high-quality solution for various high-voltage electronic systems.
Comprehensive Parameter Match with Enhanced Reliability, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the STFU11N65M2, the VBMB165R07S achieves excellent electrical parameters, ensuring robust performance for high-voltage applications:
Firstly, the drain-source voltage is 650V, matching the original model, providing sufficient safety margin in industrial environments with voltage fluctuations and transient overvoltage risks.
Secondly, the continuous drain current is 7A, equal to the original model, ensuring adaptation to high-power circuit designs.
Thirdly, the on-state resistance is 700mΩ (@10V gate drive), coupled with advanced SJ_Multi-EPI technology that optimizes switching losses and efficiency, delivering performance on par with the STFU11N65M2's 680mΩ. Additionally, the VBMB165R07S supports a ±30V gate-source voltage, offering stronger gate ESD and noise immunity. The 3.5V gate threshold voltage design balances driving convenience and switching reliability, perfectly matching mainstream driver ICs without requiring circuit adjustments.
Enhanced with Advanced SJ_Multi-EPI Technology, Reliability and Stability Upgraded.
The core advantage of the STFU11N65M2 lies in the low on-resistance and high switching performance brought by its MDmesh M2 technology. The VBMB165R07S employs the industry-leading SJ_Multi-EPI process, optimizing device reliability across multiple dimensions. The device undergoes 100% avalanche testing and high-voltage screening, exhibiting excellent avalanche energy performance. It can handle energy surges during high-voltage turn-off, reducing the risk of device damage. Through optimized intrinsic capacitance design, it reduces charge/discharge losses and enhances dv/dt tolerance, matching the application scenarios of the STFU11N65M2. Even under harsh conditions like high-frequency switching, it maintains stable operation. Furthermore, the VBMB165R07S features an ultra-wide operating temperature range of -55°C to 150°C, adapting to complex working conditions. Having passed rigorous aging tests and long-term reliability verification, its failure rate is below the industry average, providing solid assurance for long-term operation—suitable for critical fields like industrial control, medical equipment, and emergency power supplies.
Fully Compatible Package, Enabling Seamless Replacement.
For downstream enterprises, a core concern is the R&D investment and time costs in replacement. The VBMB165R07S addresses this through package design. The device uses a TO-220F package, which is fully compatible with the STFU11N65M2's TO-220FP package in pinout, dimensions, and heatsink structure. Engineers need not modify the original PCB layout or thermal design, achieving "plug-and-play" replacement. This compatibility reduces verification time—sample validation can be completed within 1-2 days. It avoids increased production costs from PCB revisions and ensures no changes to product structure, eliminating re-certification needs. This shortens the supply chain cycle, helping enterprises quickly achieve substitution and seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to the unstable supply chain of imported components, 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 VBMB165R07S.
