In various medium-voltage, high-current application scenarios such as switch-mode power supplies, motor drives, DC-DC converters, automotive electronics, and industrial controls, onsemi's FDP2552, with its PowerTrench™ technology, low on-resistance, and high efficiency, has long been a significant choice for engineers worldwide during design selection. However, against the backdrop of global supply chain disruptions and trade uncertainties in the post-pandemic era, this imported component has gradually exposed pain points: extended lead times, procurement costs affected by exchange rate volatility, and slow technical support responses. These issues constrain production schedules and cost control for downstream enterprises. Given this demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, with years of deep cultivation in power semiconductors, has launched the VBM1154N N-channel power MOSFET based on independent R&D. This product precisely对标es the FDP2552, offering core advantages of parameter upgrades, technological parity, 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 solution for medium-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the FDP2552, the VBM1154N achieves across-the-board improvements in key electrical parameters, delivering robust performance for high-current applications:
Firstly, the continuous drain current is increased to 50A, significantly surpassing the original model's 37A—a 35% enhancement in current-carrying capability. This enables effortless handling of higher power loads, improving system stability and supporting upgrades to more demanding designs.
Secondly, the on-state resistance is reduced to 30mΩ (@10V gate drive), lower than the FDP2552's 36mΩ (@10V, 16A). This reduction minimizes conduction losses, directly boosting overall efficiency and reducing heat generation in high-frequency or high-current operations.
Thirdly, the drain-source voltage remains at 150V, matching the original, ensuring reliable performance in medium-voltage circuits. The gate-source voltage of ±20V offers stronger gate ESD and noise immunity, preventing unintended turn-on in noisy environments. The 3V gate threshold voltage balances driving ease and switching reliability, seamlessly compatible with mainstream driver ICs.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the FDP2552 lies in the low on-resistance and fast switching provided by PowerTrench™ technology. The VBM1154N employs advanced Trench gate process, building upon excellent switching characteristics while optimizing reliability. The device undergoes rigorous pre-shipment testing, including avalanche energy and high-voltage screening, ensuring durability under transient conditions. Through optimized intrinsic capacitance design, it reduces switching losses and enhances dv/dt tolerance, matching the FDP2552's application scenarios. With an operating temperature range of -55°C to 150°C and passing 1000-hour high-temperature/high-humidity aging tests, it offers long-term stability for harsh environments like automotive and industrial systems.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
The VBM1154N uses a TO-220 package, identical to the FDP2552 in pinout, dimensions, and heatsink structure. Engineers can directly replace the component without PCB layout changes or thermal redesign, achieving plug-and-play substitution. This compatibility slashes verification time to 1-2 days, avoids costs from design modifications, and accelerates supply chain integration, helping enterprises quickly adopt domestic alternatives.
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产业链 with production bases in Jiangsu and Guangdong, ensuring stable mass production. Lead times for VBM1154N are within 2 weeks, with expedited 72-hour delivery for urgent orders, mitigating risks from logistics, tariffs, or geopolitics.
