In various low-voltage, high-current application scenarios such as power management systems, motor drives, battery protection circuits, and DC-DC converters, ROHM's RS1E280BNTB, with its low on-resistance and high current capability, has been a significant choice for engineers worldwide. However, in the post-pandemic era, this imported component faces challenges like unstable lead times, procurement costs affected by exchange rate fluctuations, and slow technical support responses. These issues constrain production schedules and cost control for downstream companies. Given this industry demand, domestic substitution has become a necessity for ensuring supply chain security and enhancing competitiveness.
VBsemi, with years of expertise in power semiconductors, launches the VBQA1302 N-channel power MOSFET based on independent R&D. This product precisely targets the RS1E280BNTB, 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 solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the RS1E280BNTB, the VBQA1302 achieves leapfrog improvements in key electrical parameters, offering robust performance for high-current applications:
Firstly, the continuous drain current is increased to 160A, significantly surpassing the original model's 28A—a 471% enhancement in current-carrying capability. This enables effortless adaptation to higher power-level designs, improving system stability and reliability.
Secondly, the on-state resistance is as low as 1.8mΩ (@10V gate drive), superior to the RS1E280BNTB's 2.3mΩ. This reduces conduction losses, improving overall efficiency and reducing heat generation in high-frequency switching applications.
Additionally, the VBQA1302 supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity. The 1.7V gate threshold voltage design balances driving convenience and switching reliability, matching mainstream driver ICs without requiring drive circuit adjustments.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the RS1E280BNTB lies in its low on-resistance and high current handling. The VBQA1302 employs advanced Trench technology, optimizing device reliability across multiple dimensions. It undergoes rigorous testing before leaving the factory, exhibiting excellent performance in high-current conditions. Through optimized design, it reduces switching losses and enhances dv/dt tolerance, ensuring stable operation even under harsh conditions. The VBQA1302 features an operating temperature range of -55°C to 150°C, adapting to various complex environments. Having passed long-term reliability tests, its failure rate is below industry average, providing solid assurance for critical applications like automotive electronics, industrial control, and consumer devices.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
The VBQA1302 uses a DFN8(5X6) package, which is fully compatible with the RS1E280BNTB in terms of pinout, dimensions, and thermal characteristics. Engineers need not modify PCB layouts or thermal designs, achieving "plug-and-play" replacement. This compatibility reduces verification time to 1-2 days, avoids PCB revision costs, and eliminates re-certification needs, shortening the supply chain cycle for quick substitution.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components, VBsemi leverages China's semiconductor industry chain, with production bases in Jiangsu and Guangdong, enabling stable mass production. The lead time for VBQA1302 is compressed to within 2 weeks, with emergency orders enabling 72-hour delivery. This mitigates risks from supply chain volatility and trade policies. As a local brand, VBsemi offers professional technical support with "one-on-one" services, providing technical documentation, substitution reports, and circuit optimization solutions. Technical issues receive rapid response within 24 hours, addressing slow support from imported components.
From power management and motor drives to battery protection and DC-DC converters, the VBQA1302, with its core advantages of "superior parameters, stable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the RS1E280BNTB. It has gained market recognition in leading companies. Choosing VBQA1302 is not just a component replacement; it is a crucial step for upgrading supply chain security, optimizing costs, and enhancing competitiveness—requiring no R&D risks while enjoying better performance, stable supply, and convenient support.
