In various high-voltage, high-frequency application scenarios such as industrial motor drives, switch-mode power supplies, inverters, and renewable energy systems, MICROCHIP's APT7M120B, with its proprietary Power MOS 7 technology, low RDS(ON) and Qg design, and inherent fast switching speed from the patented metal gate structure, has been a significant choice for engineers worldwide. However, against the backdrop of intensified global supply chain disruptions and frequent international trade frictions in the post-pandemic era, this imported component has gradually exposed numerous pain points: unstable lead times, procurement costs susceptible to exchange rate fluctuations, and lagging technical support responses. These issues severely constrain downstream companies' production schedules and cost control. 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, enhance efficiency, and improve core competitiveness.
VBsemi, with years of deep cultivation in the power semiconductor field, has launched the VBP110MR24 N-channel power MOSFET based on its independent R&D capabilities. This product precisely targets the APT7M120B, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without any 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 Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the APT7M120B, the VBP110MR24 achieves targeted, leapfrog improvements in key electrical parameters, offering more robust performance guarantees for high-voltage applications:
Firstly, the continuous drain current is increased to 24A, surpassing the original model's 22A—a 9% enhancement in current-carrying capability. This enables effortless adaptation to higher power-level circuit designs, whether upgrading existing equipment or improving system operational stability.
Secondly, the on-state resistance is significantly reduced to 420mΩ (@10V gate drive), superior to the APT7M120B's 570mΩ—a 26% reduction. This minimizes conduction losses, directly contributing to improved overall efficiency and reducing heat generation in high-frequency switching applications, thereby lowering cooling system demands.
The VBP110MR24 supports a ±30V gate-source voltage, offering stronger gate ESD and noise immunity, effectively preventing unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage design balances driving convenience and switching reliability, perfectly matching mainstream driver ICs on the market without requiring additional adjustments to the drive circuit.
While the drain-source voltage is rated at 1000V, it remains highly suitable for a wide range of high-voltage applications, providing reliable performance where voltage margins are adequately managed, coupled with enhanced current and resistance characteristics for superior overall system efficiency.
Enhanced with Advanced Planar Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the APT7M120B lies in the low losses and fast switching speed brought by its Power MOS 7 technology. The VBP110MR24 employs advanced Planar gate process technology, building upon excellent switching characteristics while optimizing device reliability across multiple dimensions. The device undergoes rigorous avalanche testing and high-voltage screening before leaving the factory, exhibiting robust avalanche energy performance. It can handle energy surges generated during high-voltage turn-off, reducing the risk of device damage. Through optimized intrinsic capacitance design, it reduces charge/discharge losses during switching and elevates dv/dt tolerance, matching the application scenarios of the APT7M120B. Even under harsh conditions like high-frequency switching, it maintains stable operation. Furthermore, the VBP110MR24 features an ultra-wide operating temperature range of -55°C to 150°C, adapting to industrial high-temperature environments and extreme climates. Having passed long-term reliability verification, its failure rate is below the industry average, providing solid assurance for critical fields such as industrial motor drives, renewable energy systems, and power supplies.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment and time costs involved. The VBP110MR24 fundamentally addresses this through its package design. The device uses a TO-247 package, which is fully compatible with the APT7M120B's TO-247 package in pinout, dimensions, and heatsink structure. Engineers need not make any modifications to the original PCB layout or thermal design, achieving "plug-and-play" replacement. This compatibility reduces substitution verification time to 1-2 days, avoids costs from PCB revisions, and eliminates re-certification needs. It 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 established semiconductor industry chain, with modern production bases in Jiangsu and Guangdong. This enables full-process independent R&D and stable mass production of the VBP110MR24. Lead times are compressed to within 2 weeks, with emergency orders enabling 72-hour rapid delivery, mitigating risks from international volatility and tariffs.
